Subroutine simulation migration from HETVAL to UMATH

[paulusrex]

Hi!

I'm already simulating a shape memory alloy behavior with the aid of the HETVAL subroutine, but I'd like to use UMATHT instead, since the HETVAL can't simulate correctly heat absortion(cooling down).

I've tried to add the required values for UMATHT without achieving a correct phase fraction simulation, and some times even no compilation of the .for file.

Is there any other examples that uses UMATHT besides the Stefan problem?
Any other recommendation about HETVAL to UMATHT migration?

Thanks in advance!
