Fortran for Abaqus

Hello,

I'm working with Abaqus and Fortran to be able to develop user materials.

My model works because I'm able to realize calculations. But, when I realize many calculations (around 5 or 6, it depends) an error appears.

The error is "La ligne entrée est trop longue" that is to say the order line is too long. When I close the window and re-open it, the very same calculation works and after something like 5 calculations the same error appears again.

I don't manage to see where comes from the problem.

Does someone had this probleme and solved it ?

Best regards,

Simon
