After verifying both the Abaqus Standard and Explicit with the use of subroutines, I tried to run a model study using a UMAT subroutine. However, only one subroutine that lacks PROPS works for me (in the picture it calls UMAT.for) (i.e. the one where I don't have to use the Abaqus user stuff command to apply the values to those PROPS), while one that does contain them I gives a compilation error (in the picture it calls UMAT1.for).

Would anyone know the reason why this happens?
