Description

I'm looking for a wrapper for calling ExaCMech from Abaqus/UMAT for two reasons.
First, the wrapper will make ExaCMech more accessible to many users of UMAT. Nowadays, UMAT can be called from several FE/FFT codes, including ExaConsist. Second, ExaConsist is still being improved to support periodic boundary conditions, controlled triaxiality, and Lode loading conditions. While these features are being implemented, a wrapper for ExaCMech will allow users to run jobs in Abaqus using ExaCMech's material models.

Research direction

The issue names no files or tests. Start by mapping ExaCMech’s material-model interface and the UMAT/ExaConsist context described in the issue, then confirm the Abaqus calling and build requirements. Done means a defined, working wrapper that lets Abaqus jobs use ExaCMech material models.
