Subroutines in CalculiX not only may have a different syntax but they require recompiling CalculiX from the source code. But you can find some ready-made examples and workarounds. This thread might be helpful: [UMAT option in PrePoMax](https://prepomax.discourse.group/t/umat-option-in-prepomax/606)

PrePoMax is not a problem here as you will only need to configure CalculiX properly and add necessary keywords - you can just use the keyword editor for that.

Also, it might be good to ask on the CalculiX forum. Someone there should have more experience with CalculiX subroutines.
