Good afternoon, i am trying to solve 2D problem of crack propagation in a plate. I have a code that used to work in previous versions of ANSYS but later it started to fail with the problem: "Requested data is not stored for node 6.

Line= *GET, SIGMA, node, num, s, y

The *GET command is ignored. "

The code is shown bellow.
