Hi everybody,

 

I am currently working on automating an optimazation process for a composite structure with the Solver OptiStruct and HyperWorks Version 2017.3 . Therefore i need to programm a python script which whom i can get the Normal X and Y Stresses of CSTRESS.

 

What i have tried:

I checked the OUTPUT-BOX in LOADSTEPS an then checked CSTRESS. The output format i choosed is PUNCH (its the only one i can read with an normal texteditor, right?). TYPE = ALL; NDIV = 1; OPTION = ALL. After the optimazation i opened the .pch file, but the only stress i can allocated is the von Mises Stress i dont want to know.

 

Can somebody tell me where i can find the Normal Stresses, optional the other Stresses and optional the CSTRAIN and CFAILURE?

 

 

I thank you in advance.

    Hi,

     

    The SOUT field on the PCOMP or PCOMPG Bulk Data Entry must be set to YES to activate stress results calculation for the corresponding ply. For PCOMPP, the SOUT field on the corresponding PLY entries should be set to YES.
