I have written my UMAT using silverfrost FTN95 and made a model by abaqus 6.13. When I make a job and upload the UMAT file manually I get compilation error: 

" 'ifort' is not recognized as an internal or external command,operable program or batch file."

But when I include the UMAT using abaqus command window it says that subroutine file is missing.

How can I solve this problem? Should I change the compilation command in abaqus .env file?

Thanks in advance
