Hello, thank you for addressing my previous concerns. The mesh for the model seems to have been resolved, but there are still issues with convergence and force conduction.
Below is the message I received after solving in WORKBENCH:
- The solver engine was unable to converge on a solution for the nonlinear problem as constrained. Please refer to the Troubleshooting section of the Help System for more information.
- The solution failed to solve completely at all time points. Restart points are available to continue the analysis.
- Although the solution failed to solve completely at all time points, partial results at some points have been able to be solved. Please refer to the Troubleshooting section in the Help System for more details.
- The unconverged solution (identified as Substep 999999) is output for analysis debug purposes. Results at this time should not be used for any other purpose.
- The work load is highly imbalanced for this Distributed Ansys solution, due to the contact elements in (Tw - L chuck). This will negatively impact the scaling at higher core counts. You may select the offending pair via RMB on this warning in the Messages window.
- One or more MPC contact regions or remote boundary conditions may have conflicts with other applied boundary conditions or other contact or symmetry regions. This may reduce solution accuracy. Tip: You may graphically display FE Connections from the Solution Information Object for non-cyclic analysis. Refer to Troubleshooting in the Help System for more details.
- Two or more remote boundary conditions are sharing a common face, edge, or vertex. This behavior can cause solver overconstraint and is not recommended, please check results carefully. You may select the offending object and/or geometry via RMB on this warning in the Messages window.
- The Combine Restart Files property under Analysis Settings needs to be set to Yes if the core number is modified for a Restart Analysis.
