Hi,
this would be an "inconditional" stop which would cause the "irregular" shutdown of Ansys and the loss of the calculated data. It's OK for linear analyses, but not the recommended way for non-linear.
If you want to perform a restart, you can place a text file named "<jobname>.abt" in the working directory. You have to write the word "nonlinear" without quotes on the first row, starting at column 1. The execution will stop after the current equilibrium iteration.
Regards
