How to automatically terminate an ANSYS run as soon as a certain value is reached?

    • FordPrefect

      Hello everybody,

      I am looking for a way to terminate an analysis run automatically as soon as a certain check value has been reached. When using the arc-length method there is the command ARCTRM. The command may be used to detect the limit load; or it terminates the analysis as soon as a defined DoF reaches a defined value. However, I would like to terminate the analysis automatically as soon as there is more than, let's say, 5% plastic strain in a certain region of the model. A workaround when not using arc-length could be a restart-cascade: stopping after each substep, checking the data, and restart again. This could be done in APDL but it is tedious, and slow. Also, the arc-length method does not support the restart capabilities of ANSYS.

      Is there a way to script a user subroutine for the solver for this task? I fancy something like the result tracker tool but not limited to a single node and with additional abort criterion. I have to admit that I am not overly familiar with any other programming language than APDL and a little bit of Python.

      Thanks for your support!

      Kind Regards

      Andreas Panenka
