Applies To Product(s): AutoPIPE, Version(s): 2004, XM, & V8i Environment: N/A Area: Import Subarea: Original Author: Bentley Technical Support Group Import and export of piping models between CAD and AutoPIPE can save man hours in the creation and checking of piping and structural models and prevent errors associated with manual entry of piping models. AutoPIPE can directly import CAD piping models from AutoPLANT (PXF, with additional PXD& PXH data), AutoPLANT Designer/Isometrics, ProPIPE, Caesar II Neutral (CII), and Aveva PDMS (CII). In addition, AutoPIPE can import structural steel models from Bentley STAAD and Multi-Steel; if the Multi-Steel model is composed of AISC structural elements in order to consider mass and flexibilities of structural supports as part of the piping analysis. In addition, Bentley's CAE development team has produced a number of translators to convert other well known CAD system files to be opened by AutoPIPE. Please see the list of translators that are installed with Bentley AutoPIPE V8i 9.1.1.2 and higher: 1. PCF to AutoPIPE current version v1.0.0.36, Dec 2013 The PCF translator will translate SmartPlant, Autodesk Inventor, CADWorx, Solidworks, Catia and Medusa PCF file formats. SmartPlant does have a richer data format which supports component stress attributes like: pressure, temperature, pipe weight, insulation etc. The PCF files generated by the other products mentioned only support geometry coordinates and nominal pipe size. We have found several 3rd party applications like Autodesk Inventor may not write a valid PCF files and the PCF translator will do the best conversion it can, but in these cases Autodesk would have to improve the quality of their exported PCF file. This translator will only work with the PCF file created from one the multiple applications listed above. You may need to contact the application technical support to get a step by step procedure to create a PCF file. Some may even need a software add-on installed (like Solidworks needs an add-on called Routing that allows the user to model piping routes, which can then be transferred to AutoPIPE). 2. ADLPipe to AutoPIPE current version v.1.0.0.15, Aug 2012 ADLPipe Pipe stress program used primarily in the nuclear power industry, converts ADL PIPE models to an *.ntl file format to be opened by AutoPIPE. Originally released in 1967, ADLPipe was the first commercially available piping analysis program and was bought by Bentley in 2008. 3. Intergraph PDS to STRAIT to AutoPIPE current version v.6.0.0.13, Aug 2013 PDS is a comprehensive, intelligent computer-aided design/engineering (CAD/CAE) application for plant design, construction, and operations. There is some configuration. With any PDS setup there is usually an amount of custom configuration of CAD components. The user is also required to install 2 PDS configuration files on the PDS side to generate a readable PDS stress neutral file. Therefore any out-of-box solution may not work the first time. Since Intergraph PDS has typically a high level of customization we recommend translating a few PDS models for you first to help configure the component mapping. PDS Stress Analysis Interface: (PD_Stress - PDS model neutral file (*.n) - STRAIT - AutoPIPE model neutral file (*.ntl) - AutoPIPE program - AutoPIPE model file (*.dat) These translators will be installed to the following folder:. C:\bentley\AutoPIPE Translators \ADLPipe Translator \PCF Translator \STRAIT Attention: If you had not installed AutoPIPE V8i 9.1.1.2 or higher and would still like to have the translators, please log a service request asking for the respective translator. All translators have a reference manual included with-in each zip / installation folder for further details information. If you encounter any problems or have some comments, please report them back to use so we may continue to provide the best possible solutions for our users, such as yourself.

Wiki Page: STRAIT Translator in AutoPIPE
Applies To Product(s): AutoPIPE, Version(s): 2004, XM, & V8i Environment: N/A Area: Subarea: Original Author: Bentley Technical Support Group STRAIT (PDS) to AutoPIPE Translator - Version and Features Overview The STRAIT Translator program is required to convert a Intergraph PDS 3D piping model to AutoPIPE. This includes geometry, pipe sizes, wall thickness, materials, insulation, supports, valves, flanges, weights etc. The STRAIT Translator is provided, at no charge when AutoPIPE V8i is installed. This application requires a little effort in setting up. This process usually takes about 2-3 iterations to make modifications to the companies PDS Custom configuration and/or STRAIT mapping, since every company has their own unique PDS customization. See the following Data Sheet for complete details on the application. To name a few companies that are saving time and money using this application to convert files from PDS to AutoPIPE: Air Products Nooter Ericksen Misi Setia Oil & Gas Sdn, Bhd Worley Parsons (Australia) Bechtel San Francisco Fluor Lurgi (Germany) Burns & McDonnell Chiyoda Conversion process: PDS Stress Analysis Interface PD_Stress - PDS model neutral file (*.n) - STRAIT - AutoPIPE model neutral file (*.ntl) - AutoPIPE program - AutoPIPE model file (*.dat) Download the following avi to view this process : click here We have found in the past if we send the STRAIT software to users to evaluate, very soon they come back and insist it does not work and do not pursue the Bentley software product. This is why we prefer to translate several of your PDS models to AutoPIPE, let you review the translated AutoPIPE model vs. the original PDS model to give confidence in the accuracy and completeness of the stress model, and then send all the completed configuration files.. As mentioned, with any PDS setup there is usually an amount of custom configuration of CAD components. Therefore any out-of-box solution may not work the first time. We would suggest: Download and install STRAIT: STRAIT is now bundled with Bentley AutoPIPE download and installation. Please follow the procedure to download and install the current version of Bentley AutoPIPE. AFter installation Generate a PDS model neutral file: First make sure that the Intergraph PDS pipe stress extraction module is installed. Intergraph calls it PD_STRESS or a similar name. Many PDS users have not even installed this module which comes standard with PDS. Select an example PDS model that you would like to extract. Make sure that it has gone through a consistency check good enough to extract an Isometric. The name of the Intergraph defaults file is DEFAULTS.DAT. Do not use defaults.dat, but instead use the attached defstr.dat and strmap.tbl files NOTE: Ensure the following path in the DEFSTR.DAT file points correctly to the STRMAP.TBL c:\win32app\ingr\pdstress\dat\strmap.tbl !PDS TO STRESS MAP [modify path as necessary] Once the .n file has been created, load it into the STRAIT program. NOTE: Please note that there is a facility within Intergraph PDS which allows users to assign a stress ID to an entire system for extraction of pipe stress neutral files as an alternative to extracting 1 line at a time. The documentation still shows information on the old DOS STRAIT version but the options are all the same. Typical detailed procedure to Create PDS stress neutral file either by line number or Stress_system_no. AFTER the configuration above hass been completed. Revise segment data Define Active Group…search criteria…fluid code … Identify reference point and data any point in the model…and accept it will highlight the piping in the active group defined Toggle brief segment data to see the complete segment data list and revise the stress_system_no On PD shell - pick Pipe Stress Analysis Fill in model name and stress_system_no under pipeline names Note: The pipeline names = line number if word 12 = 0 or 2 in defstr.dat .n file will be created in the stress output node path Convert a PDS file to AutoPIPE file format: Start STRAIT, select Browse button, locate the systemname.N file created from PDS and select the Open button. Press the edit button to modify the configuration settings, press OK button to get back to the main screen. Press the Convert button to start the conversion process. You should see the conversion status screen scrolling and then after a short time, stop scrolling. If all the configuration files and settings were correct, you should see: Neutral File Successfully Processed. ( If not, more modifications to the configuration files and / or settings is required). When successfully converted, an AutoPIPE model neutral file ( systemname.NTL ) is created in the STRAIT folder or designated folder.. Copy the systemname.NTL file to a new folder for your AutoPIPE models. Open AutoPIPE, select File Open AutoPIPE Batch (.NTL), locate your newly created systemname.NTL file, press Open button. The model should now appear. Select File Save, this will generate the AutoPIPE model file ( systemname.DAT ). LIMITATIONS: Cannot create PDS stress neutral file for disconnected lines Component limit of 800 which is roughly 800 nodes as well. Unknown components mapped to pipe ID = RIGID Possible disconnects in PDS model = unstable system in AutoPIPE Mapping a dummy leg to a frame cannot be done. Mapping a hanger to a tie rod is not possible to map to a tie-rod since it must have a connected to point instead of ground. Line numbers - 14 characters can be used mix of alpha-numeric and numeric.

Wiki Page: AutoPIPE's ADL PIPE Translator Limitations
Applies To Product(s): AutoPIPE, Version(s): 2004, XM, & V8i Environment: N/A Area: import Subarea: Original Author: Bentley Technical Support Group Conversion Limitations for AutoPIPE's ADL Pipe translator Note: The following information was copied directly from the a document that was placed on the computer when AutoPIPE and the translators were installed: C:\ Bentley\ AutoPIPE Translators\ ADLPipe Translator\ ADLPipe to AutoPIPE Translator User Reference.pdf 1. Some supports do not translate. Warnings are given where these occur. 2. ASME Mixed Class analysis, and Displacement Time History analysis are supported by AutoPIPE but is not supported by the translator. 3. Sub Space iteration is not supported by AutoPIPE. 4. An ADLPipe elbow/bend can have up to 9 mid points whereas AutoPIPE supports only 1 node point. Elbow mid points are not translated. 5. All note instructions are ignored and no comments are brought forward. 6. A PIPE or CH instruction with either of I1, I2 or both missing or set to zero is not supported. 7. Limited support for Mitre bends is given. 8. Type of all valves and flanges imported is set to Non Standard. No pressure rating available in ADLPipe. 9. BEAMS are imported as RIGID pipes so section properties are not mapped. 10. A ‘0’ cannot be supported as a node number in AutoPIPE. Change the node number in the ADLPipe file before importing. 11. The Anchor instruction is to be used to define the relative positions of the Anchor points. If it is used with 0,0,0 as the X Y Z coordinates then all other points will be with reference to this as the origin. If another Anchor instruction is specified with 0,0,0 then this will also be located at the origin. In ADLPipe ‘0’ sometimes means ignore or do not change, AutoPIPE takes this as meaning zero. Either delete the anchor locations without correct coordinates or remove the 0,0,0 from the definition. 12. The stress range reduction factor ‘f’ is mapped to a default value of 1.0 in AutoPIPE as there is no NTL field available to map the actual value. 13. Only fully defined user SIF instructions can be supported. Partially defined SIF’s are ignored. 14. ADLPipe has no limit on the number of load cases. AutoPIPE does! 15. Mapping for several NEWFILE types not available in AutoPIPE. - NEWFILE methods we are able to map are: ADLPipe Method = 1 Square root sum of squares (SRSS) = 2 Algebraic sum = 3 Absolute sum = 4 Absolute value of algebraic sum = 9 Peak search - Methods not currently supported. ADLPipe Method = 5 Sum of signed (F1) and unsigned (F2) load sets = 6 Difference (Range) = 7 Absolute value of range = 8 Factorin = 10 Maximum +ve search = 11 Maximum -ve search = 12 Remove file from tape 14 = 13 Maximum +ve search for support and restraint = 14 Maximum -ve search for support and restraint = 15 Absolute difference 16. AutoPIPE can only have one sustained case, so if there are multiple DEADWEIGHT load cases in ADLPipe input, we only consider the first one. 17. ACCELERATION (static earthquake) is mapped to Occasional load in AutoPIPE. Its value is fixed and cannot be changed as in ADLPipe, so we just take forward the initial value at first node in the model and ignore all the changes. 18. Multiple Response Spectra analysis is supported by AutoPIPE but mapping is currently not available. 19. For spectrums interpolation Lin-Log method is not supported by AutoPIPE. 20. The stress summaries are translated from ADLPipe and written in an XML file in the same model directory. These summaries are available for ASME Class 1, 2 and 3. Stress Summary for B31.1 is not supported in AutoPIPE. The stress summaries contain load case combined. Every equation expects a particular type of load cases that can be combined to give stress report. If the load cases supplied by the user are not of the correct type, AutoPIPE may not accept these load cases from the translated .XML file. The translated stress summary contains service levels, load cases and number of cycles for which the load cases are combined per equation .... see document for complete details.

Wiki Page: AutoPIPE Powered by ADL PIPE
Applies To Product(s): AutoPIPE, Version(s): 2004, XM, & V8i Environment: N/A Area: import Subarea: Original Author: Bentley Technical Support Group Questions and answers about the difference between AutoPIPE and ADL PIPE 1. What part of ADL PIPE is used by AutoPIPE? Answer: ADL PIPE was acquired by Bentley in 2005 to provide a good solid ground with which to add a nuclear version of AutoPIPE. The was a perfect marriage of two programs, anyone who has used ADL PIPE knows that the graphical side was lacking but the calculations performed by ADL PIPE were used by industry since the 1969. The nuclear solution routines from ADL PIPE form AutoPIPE's Nuclear solution. 2. What are the major difference between the programs? Answer: See the following: AutoPIPE's ADL PIPE Translator Limitations AutoPIPE doesn't allow the Static Earthquake value to alter from one member to another, ADLPipe does. AutoPIPE can only have one Gravity case, ADLPipe is unlimited and is also unlimited on the number of other load case, where as AutoPIPE has hard load case limits. Some model combination methods are not supported by AutoPIPE. AutoPIPE can only insert springs vertically, ADLPipe can have them in any direction. 3. What should users do after importing a model from ADL PIPE into AutoPIPE? Answer: You should confirm the loadings have come over correctly and that the dead-weight result are the same. Some analysis settings may be set by default in ADLPipe and AutoPIPE and these should be the same (i.e. Tool Model Options General, Edit, Results..). 4. Why are my results different in AutoPIPE from ADL PIPE? Answer: In most common cause, the translated AutoPIPE model is different from the ADL PIPE model (confirm the model listing are exactly the same in both programs). In addition, user's should consider all the information mentioned in the following document that was installed with the ADL PIPE translator: C:\ Bentley\ AutoPIPE Translators\ ADLPipe Translator\ ADLPipe to AutoPIPE Translator User Reference.pdf 5. Has Bentley performed any benchmark calculations to check the AutoPipe values compared to the ADL values?" Answer: As mentioned above, the ADLPipe solver is what we use to drive the nuclear solution. Bentley CAE development team did do some benchmarking between the two products and in the end NRC made us validate AutoPIPE Nuclear separately as essentially the two solutions were the same. There are some standard NRC and ASME verification examples that have been carried out also by both products. The AutoPIPE Acceptance Test Set (ATS) has some test models to use to verify the installation. Also, AutoPIPE QA&R subscribers have access to more information about the program than normally available. With regard to importing ADLPipe models; this can be done using the ADLPipe translator that is an option to be installed with AutoPIPE V8i Standard, Advanced, or Nuclear. There are some limitations and omissions, but on the whole around 95% translation should be possible. There are going to be differences in the results; the translation process makes certain assumptions and the two applications do many things in slightly different ways including presenting the results.

Applies To Product(s): AutoPIPE, Version(s): 2004, XM, & V8i Environment: N/A Area: Modeling, Support Subarea: Original Author: Bentley Technical Support Group Problem: How to model piping held by 2 rigid structural supports members as shown below: Answer: Before starting a modeling approach it is important to answer the basic questions: How does the support function? What are some assumptions about the support? etc.. There are 2 methods of modeling approach here: 1. Assume that the pipe support is held Rigidly in place by the structure, but the structure is not model: a. Model Piping in AutoPIPE with node points where the supports are placed. b. use the philosophy mention in the following AutoPIPE help section: Help Contents Contents Tab Modeling Approaches Modeling Approaches Support Model 3: Rod Support. Note: 2. Assume that the pipe support is held in place by the structure, modeling both pipe and support structure: a. Model Piping in AutoPIPE with node points where the supports are placed. b. Model Structure in AutoPIPE using Beam Section Properties as per your design from where the structure is attached to the piping surface continuing back to some node points that can be assumed as an anchor location. c. Attach both incline supports mentioned in the online help for : " Model 3: Rod Support.", to the beams as shown below. Procedure: Select Pipe node point, press Insert Support : "Support Type" = tie/link, "Connect to" = specify beam node point "Weight" = account for the clamp weight by dividing it up among the 2 supports. 1/2 the weight of the coupling steel for each support "Spring rate" = manual calculation or assume "Rigid" "Gaps" = 0 "Friction" = for user to decide, low value free to move in the axial direction, high value restricts movement in the axial direction. "Gap Settings" = Weightless Notes: 1. Keep in mind that a pipe and beam/frame are not connected just because they appear connected. Beam / Frame structures are only connected to the piping by 1 of 2 methods: a. Specifying a pipe node point as a beam's Point I or J entry b. Inserting a support on the piping where the "Connect to" = a beam node point. d. Insert another beam connecting the 2 angular beams together. The extra horizontal beam (M8) shown in the image above, fulfills the role of the circular clamping steel, as a connection point for the 2 angular beams support and preventing the 2 beams from separating / uniting. e.

Wiki Page: Modeling Pipe-Structure Interaction in AutoPIPE
Applies To Product(s): AutoPIPE Version(s): v6.20.09 and higher Environment: N/A Area: Modeling Subarea: N/A Original Author: Mark Upston, Bentley Technical Support Group Overview The mass and flexibility of structural supports can have a profound impact on the piping stress analysis. In many instances, if the support structure deflects only a fraction of an inch, it can affect piping moments to the extent where hangers can be eliminated, and/or piping loads on equipment nozzles and supports can be significantly altered. In addition, consideration of structural support flexibilities changes the natural frequencies of the piping system. Modeling pipe/structure interaction as part of piping stress analysis Despite the fact that structural support flexibilities can have a significant impact on piping loads and stresses, most piping engineers do not consider these flexibilities in their piping stress, analysis. Typically, structural supports are modeled as simple supports such as rigid guides, vertical stops, line stops, etc. with no consideration given to the flexibility of the support itself. Although AutoPIPE allows engineers to input a stiffness as part of the support element, the piping engineer often does not have convenient access to structural support details needed to calculate support stiffness'. As a result, the support is typically treated as rigid. As an alternative to using simple supports, AutoPIPE enables engineers to easily build the support structure into the piping model in order to consider pipe/structure interaction. The structural modeling is done within the piping model itself and takes advantage of AutoPIPE's graphical user interface, Using AutoPIPE's ability to graphically copy & paste between separate jobs or within the same job, users can now create libraries of common support structures and paste them into their new model in seconds . We will explain later AutoPIPE's unique abilities in defining the relationship between piping and structural steel. AutoPIPE users are riot burdened with going back and forth between separate programs or batch files to model support structures. Currently, AutoPIPE supports the American Institute of Steel Construction cross, sections as well as a material properties library for common structural steel materials. Once a cross section has been interactively selected, the user immediately sees the cross sectional properties with moments of inertia from the AutoPIPE structural database as well as the steel material properties. Nonstandard cross sections or cross sectional properties for International steel shapes can be entered as nonstandard or saved in the AutoPIPE database. AutoPIPE's structural steel analysis provides beta angle options, moment releases for pinned joints, and rigid end length options. Users see the structural model graphically as it is being built. Once the support structure has been created, users can define the connection between piping and structural steel using one of AutoPIPE's 2 point supports such as a guide or a vertical stop. A user can, for example, define the support connection between node B10 on his piping system and node 21 on his support frame by connecting them with a guide from B10 to 21. From there, the user can place gaps in any direction in the event that the pipe would lift off or move, and can also input friction. The flexibility of the support structure, including friction loads, will then be considered as part of the piping analysis. In addition to piping analysis results, users can also review beam deflections, beam forces and moments.

Forum Post: A question on branch modelling
Hi I just read the article from Bently "Procedures for Modelling Branch Connections" and got some questions. In method 2 (2 point model), the tee is modelled as a normal pipe up to head OD and a rigid pipe from head OD to centre, and insert a user SIF at the surface point. In this method can I still use the SIF according to B31.3 method? Or need to get the actual SIF from FEA? If I use code SIF in this method, is it still more actuate than method 1 (normal tee connection with code SIF)? In method 3 (3 point model) a flexible joint is used to account for pipe wall flexibility. Can I use nozzle flexibility element instead of the flexible joint so that I don't need to calculate the actual stiffness? This method remind me that nozzle on vessel can be modelled in this way as well. If I use this method (nozzle pipe + nozzle flexibility element + rigid pipe to vessel centreline), do I also need to get the actual SIF on vessel surface? And can I use SIF according to B31.3? Thanks in advance.

AutoPIPE Batch (NTL) AutoPLANT (PXF) Intergraph PDS (NTL) Cadcentre PDMS (NTL) AutoPIPE Model (DAT) PlantFLOW cannot open your file unless it is in one of the formats listed above. Try to get your file into one of the above formats to be imported by the program. For additional information please review the following PlantFLOW help section: Help Contents Contents Tab Command Reference File Menu Open Opening an Existing Model. Importing AutoPIPE model Importing an AutoPIPE Batch (NTL) Input file: PlantFLOW is able to read AutoPIPE batch (text file) format (*.NTL). This has similar limitations to importing AutoPIPE database files (*.DAT). Select File/Open/AutoPIPE Batch ( *.ntl ) to load a piping system created using the batch input format (this file is in ASCII format). When the Import dialog appears, navigate to the drive and directory containing the desired *.NTL file, select it, then press Open. PlantFLOW will read the data and perform a consistency check before generating the model and associated files. Importing AutoPLANT (PXF) files into PlantFLOW AutoPLANT models cannot be generated in the DWG format. To prepare the model for import into PlantFLOW, you must first generate a PXF file using the Import/Export function as described below. Preparing the AutoPLANT 3D Model for import into PlantFLOW: 1. Load the AutoPLANT 3D Plant Design System. 2. Open the drawing you want to export. 3. Select AutoPLANT 3D/Import/Export . 4. The Import/Export menu now loads into the top-level AutoCAD menu. 5. Select Import/Export/Plant Exchange (pxf)/EXPORT . 6. The Drawing Selection Options dialog is displayed. Select All and press OK , or define a custom filter (refer to AutoPLANT’s online help for more information on drawing selection options; you can export components from a particular line number, by database field value, etc.). 7. The Import/Export Progress dialog is displayed. This dialog indicates the status of the export along with summary information such as the number of components which have been exported. After the process is complete, press OK to close the dialog. 8. You are now ready to import the PXF file into PlantFLOW. The PXF file is stored in the local PXF directory beneath the AutoPLANT 3D root. After the AutoPLANT 3D Model is ready you may proceed with import into PlantFLOW: 1. Select File/Open from the PlantFLOW menu. When the dialog displays, select Autoplant(*.pxf) as the file type, then press Open. 2. After completing the Import AutoPLANT dialog , the model is imported into the current system.

Forum Post: PXF import from AutoPLANT to AutoPIPE
There are some issues on it (AutoPIPE SS5 09.06) 1. Import to AutoPIPE still is being done without Tag data 2. For VALVE elements sometimes mass of the element is inserted, sometimes not. It looks to me that it is not for NS valves, i.e. when AutoPLANT element is not recognized in AutoPIPE Would you advise on it, please?

Comment on Model piping held by 2 rigid structural supports members
Do I have to model the structural beams as well? I wanted mainly to simulate the piping supporting.its more like i am having a main pipe and another pipe connected to it through a clamp.In CAESAR there was option called CNODE where i link the two supports together. In autopipe shall I use the tie/link support option? and if i use a rigid spring rate this means that the two points are firmly connected ?

Wiki Page: Modeling with Bentley PlantFLOW V8i
Applies To Product(s): PlantFLOW Version(s): XM & V8i Environment: N/A Area: Subarea: Original Author: Bentley Technical Support Group Comments Questions and Answers on modeling with PlantFLOW: Item #1, Question: Mainly do dust collection - 50 to 100 inlets through branches to one outlet (such as a fan).. If we know the outlet properties, can I get flow rate? Are there any limitations to the amount of inlets/outlets? Answer: We believe that this question would relate to the fact that there has to be an equal amount of known and unknown boundary conditions. There is some confusion on whether the amount of inlets vs. outlets has limitation . Item #2, Question: If I know the flow rate, does PlantFLOW have the intelligence to tell me how many restrictions I will need in my model geometry? Answer: PlantFLOW can be used to test geometry configurations by running an analysis and calculating the pressure drop in each component. However, it will not tell a user how to model the geometry based on the the needed results and inputs. Item #3, Question: If my pipe is outside at something like 100 deg C, can I input insulation, etc to calculate heat loss? Answer: For buried and exposed pipe, the user has the option of using a simple or complex heat transfer model. A complex type takes into account the effect of the pipe material and insulation. The last column in the "Component-Flow Report" seems to represent the calculated value of heat flow. Item #4, Question: Fluid library - for sewage disposal, is there any way to input the size and density of the solids that will be floating in fluids? Answer: PlantFLOW does not have the ability to do this. The user has to define the liquid in the pipe and cannot do two-phase flow. Item #5, Question: Can PlantFLOW analysis the Vacuum pipe with negative pressure?? Answer: From online help: Static pressure: Enter the absolute static pressure at this point. Negative values are not allowed. Item #6, Question: As we know we can insert a heat exchanger in PlantFLOW. Can PlantFLOW analyze heat exchanger performance or recommend the configuration of heat exchanger to meet the requirements. Answer: In PlantFLOW, a heat exchanger is modeled as a component with specific properties. With regards to analyze heat exchanger performance, perform multiple analysis making changes to the model as required to evaluate the performance of the heat exchanger. With regards to PlantFLOW recommending the configuration of heat exchanger to meet the requirements, this cannot be done with a simple heat exhanger element. Item #7, Question: What are the other two pressures (in Ctrl.pts and Initial ones) and what are relations between them? Answer: The initial flow and pressures are a starting point for nonlinear iterations. These are used for elements which you did not specify input for in the control points. Usually the initial data should be an average expected value for the all elements. Item #8, Question: What gives the maximum effect on dynamic pressure shown in output report (gas system)? It seems it is the "Base" one (Standard conditions), why? Answer: The dynamic pressure is based on the actual fluid density and velocity upstream of the element. Item #9, Question: Can PlantFLOW model on Newtonian fluids (similar to "Yogurt")? Answer: Bentley apologizes for the inconvenience, however there is no modeling approach in this version of the program (Version 06.02.00.05) See Also Bentley AutoPIPE External Links Bentley Technical Support KnowledgeBase Bentley LEARN Server Comments or Corrections?
