Hello DAMASK and ABAQUS users,
I want to run dislocation density based crystal plasticity finite element analysis in ABAQUS using DAMASK CP codes. I am able to run the simulations on the small geometries (single crystal). When I change to poly crystal I am getting the error as “Analysis is being terminated from a user subroutine” but when I check the data I found the following error ┌─────────────────────────────────────────────────────────────────────┐ │ warning │ │ 35 │ ├─────────────────────────────────────────────────────────────────────┤ │ could not get $DAMASK_NUM_THREADS │ │ BEGIN: :END │ │ │ └─────────────────────────────────────────────────────────────────────┘
Has anyone come across the above error?Any suggestions to resolve this error?
Thanks.

Hello,

First of all, you need to know the language of both coding platforms (UMAT and DMASK), and they must be the same or at least know how to convert them to another.

Secondly, according to your error “Analysis is being terminated from a user subroutine,” I think you can use more information about the UMAT subroutine. So, refer to the links below. You might find them helpful:
