hi all,

I'm working on UMAT for non-isothermal elasticity subroutine. I'm referring the UMAT pdf file by ABAQUS.

I've completed the code for isothermal elasticity. Now when I submit the job with the non-isothermal elasticity, ABAQUS gives a error as follows:

"Error in job NISOTHERM1: Problem during linking - Abaqus/Standard User Subroutines.   This error may be due to a mismatch in the Abaqus user subroutine arguments.   These arguments sometimes change from release to release, so user subroutines   used with a previous release of Abaqus may need to be adjusted.Job NISOTHERM1 aborted due to errors."

Please help me to conclude whether there's a problem with the UMAT code or we need to define/initialise solution-dependent variables using *DEPVAR in materials.

Thank you
