Applies To Product(s): AutoPIPE Version(s): ALL; Environment: N/A Area: Grids Original Author: Bentley Technical Support Group Date Logged & Current Version Nov. 2016 10.01.00.09 Problem: How to change Input thermal expansion coefficients for AutoPIPE analysis? Solution: There are 3 methods to adjust the Thermal Expansion coefficient from the default values found in the material library. Method #1: Change the value on the "Press/Temp/PipeID" Input grid. 1. Select Segments of piping where the coeff. will be updated. 2. Press the toolbar button to "Hide Un-Selected Segments". 3. On the input grid, select the " Press/Temp/PipeID " tab, furthest Left tab. 3. On that tab, locate the Case ,1 - 100, whose's coeff values will be updated. 4. The field maybe grayed out. Un-check the Auto check-box on the left side of the value will change the field so a new user value can be entered. 5. Change the values as needed. These new values update the model database immediately. Method #2: Change the value using the Modify> Operating Pressure and Temperature. 1. Select the piping where the coeff. will be updated. 2. Select Modify> " Operating Pressure and Temperature " command 3. On the dialog screen locate the temperature Case, 1 - 100, whose's values will be updated. 4. Scan down the aforementioned column until the row for Expansion values (the field maybe grayed grayed out) and un-check the "Auto" check-box on the left side of the value will change the field so a new user value can be entered. 5. Change the values as needed and press the OK button to apply the new setting(s). Method #3: Update the default values in the Material Library. See online help for modifying / updating the material libraries and change the default values as need in the SRC files before compiling them into LIB files to be used with AutoPIPE. Note: If using Pipe Properties Material = NS, the user is responsible for manually updating all fields of data on both the Pipe Properties Dialog and Press/Temp/Pipe ID dialog as needed. There is no AutoPIPE command to update any material library data that is set to manual input.
