Hi, I'm trying to apply a topology optimization to a structure in an Abaqus model (with Tosca Structure). The whole model is composed of different parts and some of the materials are described as fortran user subroutines. I'd like to run the optimization process with the user subroutines.

N.B. The structure I'd like to optimize is made of an isotropic elastic material.

On top of all that, since the simulation is very complex and takes around 7/8 hours, I have to run it on a cluster. To run it I have a pbs file where I can either specify the process of optimization as:

\\\$abq inter optimization task=\\\$opt j=\\\$name job=\\\$input cpus=\\\$ncpus

or specify the execution of a job with fortran:

\\\$abq inter j=\\\$name input=\\\$input user=\\\$fortran cpus=\\\$ncpus

Is there any way I can specify the subroutine in the optimization task too?

thank you
