For optimization my material parameter I use Isight software. I have an input file that simulates the material model via UMAT subroutine. How can I import this inp. file in the Abaqus component of Isight for optimization?
In Isight you can run the Abaqus component in different ways, you can for example use a .cae file and access it through the component to change things. Option B is to run it as if you were running it from the command line, in which case just add the user subroutine to the launch command.
I would recommend to test it first without isight to make sure the compiler, etc. is working and you can launch an analysis with subroutines from the command line.
