Hello Siddhu,
With regards to your question:
1> How to activate liberal allowables stresses?
Answer: I apologize for the misunderstanding, but I do not understand what "liberal allowable stresses" are. AutoPIPE allows the user to enter a user defined allowable stress, for some piping codes there is a Tools> Model option> Use Alt. Occ. Allow, or you could update the material allowable values. Suggest that you review the Piping Material Properties dialog, Tools> Model Options> Result/Edit Dialogs, and Tool> Combinations dialog for values and factors that would affect the allowable stress calculation.
2> Can I modify modulus of elasticity to get the loads at max temperature. (I need to know both load with cold modulus and hot modulus)
Answer: open the input grids and select the Press/Temp/Pipe ID tab, on this tab you can see various pipe property settings depending on piping code selected (for ASME b31.3: Press, Temp, Expan. Hot mod, Hot Allow, Sy, etc ). Any value that is greyed Out is retrieved from the piping material library, that is automatically updated with Temperature changes. Any value that has a white background is editable and is NOT automatically updated with temp. changes.
3> how to model the support with displacement like first support for overhead pipe supported from column (only rest) and having 5 degree of freedom
Answer: I apologize for the inconvenience but I do not understand your modeling requirements. To add support displacement you have would select the support point, press Insert>Xtra Data> impose support displacement. After that has been added you can make changes to it using the input grids> Imposed Disp. tab.
