I work with Abaqus CAE/Standard a lot!
Whenever I have tried to put the number below the *Depvar keyword to be greater than 15 (and there can be any subroutines (UMAT or USDFLD) with no coding in it, just the basic input parameters as provided by Abaqus User Subroutine Guide), the job always, without fail, aborts right away and gives me the error: "Illegal memory reference (signal 11)".
Keep in mind, there is no actual code anywhere in the user subroutine where there could be any mistake; I have tried this just as a curiosity, and just as expected, as soon as the number of dependent variable is higher than 15, it aborts right away!!!
What's the cause of this?
