I am going to implement the Tresca modell in Ansys using the usermat-function.
The provided files "USERMAT.F" and "usermat3d.F" are compiled with no problems,
and I use the ANSYS Product Launcher to start the new ANSYS.exe file.
However, when I try to run the provided test problem in the ANSYS USERMAT guide (Tension of 3D-block elements) the user defined method is not converging.
What may I do wrong?
Hoping for some answers!
