Hello,
I am currently working on some equations that I would like to incorporate into a thermo‑structural analysis while solving the model. Could you please advise whether it is possible to implement these equations through a user‑defined subroutine?
Kind regards,
ADDY
User subroutines are a solver-specific thing, so you should ask on the CalculiX forum: https://calculix.discourse.group/
You can also find some tips in existing threads there.
Perhaps this thread will also be helpful (it explains how to use subroutines without recompiling CalculiX and what is needed to use them): UMAT option in PrePoMax
PrePoMax doesn’t support subroutines in any way apart from allowing postprocessing of the results with SDVs and supporting material names with the @ character. But keywords calling subroutines, such as *USER MATERIAL, have to be added via Keyword Editor. Of course, the rest of the preprocessing can still be done in PrePoMax.
