I'm using UEL in ABAQUS. My model just has one 4-node element (defined in UEL) fixed in one end. When I'm running the UEL, it's working without any problm. But when I' trying to print out the global stiffness matrix I'm getting this error: "aborted with system error code 1073740940".
This is the way that I'm trying to print it out:
*MATRIX GENERATE, STIFFNESS
*MATRIX OUTPUT, STIFFNESS
