I calibrated a poly u mod hybrid model and attempted to validate the model using the run a series of FE simulations that MCalibration has built into its interface. When I click evaluate, the simulations fail because the UMATs dont appear to be generated. The following error appears from the abaqus .msg files:

***ERROR: USER SUBROUTINE UMAT IS MISSING

Has anyone come across this issue before?

Is it possible that the software was not installed correctly?

Can you make sure that your abaqus_v6.env file contains a line with the text usub_lib_dir?
