Dealing With Bisections in Large Deflection Analysis

How do you control bisections?

If the convergence is smooth but the solution is bisecting just before reaching the convergence criteria, you can increase the number of equilibrium iterations for the nonlinear analysis to avoid this issue.

The command snippet NEQIT, 100 can be added (in which 100 is a sample value for the maximum number of equilibrium iterations allowed for each substep). The maximum number of equilibrium iterations per substep is set between 15 and 26, depending on the physics of the problem.

However, if there are convergence issues, it would be better to debug the root cause by checking BCs, loading, case setup, etc.
