Hi
I am new to UMAT/USDFLD. My problem is that I need to write a Fortran file variation of youngs modulus. Since I am new to this User Subroutine so I wasted quite a few days in learning UMAT and later on, I got to know that USDFLD file has to be written for variation of Youngs Modulus along the thickness direction instead of a UMAT file. Now I am facing problems there. I prepared a USDFLD file (which is wrong I think as I am not a good programmer), this file is giving errors while inputting it. Please help me out. For your kind reference, I am attaching my Abaqus log file and the Fortran file that I have prepared.
