user material

[darski1]

Dear All,

1. I have converted "Input data" from the basic example in the page:
   https://mapdl.docs.pyansys.com/version/stable/examples/extended_examples/Python_UPF/python_upf_examples.html#python-upf-examples

into mapdl. At the top I also added the lines to initiate mapdl:

from ansys.mapdl.core import launch_mapdl
mapdl = launch_mapdl(port=50056, run_location='.', jobname='test_usermat', override=True)

It works perfectly for standard material:

mapdl.mp("EX", 1, 1e5)
mapdl.mp("PRXY", 1, 0.3)

Unfortunately when I call user material:

mapdl.run("/UPF,'usermat.py'")

I receive an error: Error in instance GRPC_127.0.0.1:50056.

2. Anyway, is the example correct? Isn't the command missing? What about

/usrcal,UserMat
or
mapdl.usrcal("UserMat") in my case?

Best regards,
Darek

Hi @darski1

Thank you for open this discussion!
I haven't tested UPF in a looooong time... so I might need to recheck the whole thing. I am not even sure it was working on the first place.

@mikerife have you tested the UPF routines within PyMAPDL?
