Workbench - Mechanical Structural Nonlinearities Diagnostics

•Since some nonlinear structural analyses can be challenging to solve, understanding how to diagnose non-convergence problems is critical in obtaining answers.

•

•The following will be covered in this section:

–Solver Output

–Monitoring the Solution

–Newton-Raphson Residuals

–

•The capabilities described in this section are generally applicable to ANSYS Structural licenses and above.

–Exceptions will be noted accordingly

•In Chapter 2, the Solution Information branch was introduced

–Recall that with the Solution Information branch, the detailed Solver Output from ANSYS can be reviewed, and convergence graphs, such as the Force Convergence behavior, can be plotted.
