How to use a UMAT

How to use a UMAT

How to use a UMAT

(OP)
Hi everyone,

I would like to use a UMAT to write in a file the deformation gradient of an element. To do that I create a file and then write in it.
My problem is I don't think that when I run a job, the subroutine is read (I've written "write(*,*) 'test'") but it is not written in the command prompt.

Is anyone already used a UMAT and know how to do it please? It would be great to help me solving my problem.

I have joined my .inp file and my umat.

PS: Sorry for my english.

Best regards,
Pipo

RE: How to use a UMAT

The User Subroutines Reference Manual has a section on printing messages to the message or status file.

for example:

write(6,*) 'test' will print 'test' in the .dat file
write(7,*) 'test' will print 'test' in the .msg file

etc.
