Non-convergence caused by material properties

      I am trying to simulate the tensile testing of a non-standard geometry sample. The model has been converted to a surface, and simplified to the form shown below:

      non-convergence can be caused by many factors, so troubleshooting this issue typically needs looking into the details of the model setup. I recommend that you plot the newton raphson residual force to locate the area of non-convergence. In addition, what time step size are you using? Can you use auto time step and assign a large number of time step (e.g, 1000) so that Ansys can adjust time step size when non-convergence is encountered.n
