Abaqus 2024 notes

Abaqus Error: "main.f" does not contain an Abaqus user subroutine

Abaqus Error: "main.f" does not contain an Abaqus user subroutine.

When using a user-provided material routine (i.e. user=main), then the file main.f must contain the umat subroutine. It is not enough if main.f includes another file that contains umat; it must be in main.f.

This check was not present in Abaqus 2020 and earlier.

Abaqus does something with the locale while reading config files. The locale variables propagate through SSH, through sbatch, into your jobs, and may cause the above error message. To prevent this, add the following line to your job scripts before calling Abaqus:
