For Static Structural and Transient Structural analyses, Mechanical includes a beta feature that enables you to specify an Energy Convergence criteria property. This new property is available in the Nonlinear Controls category of the Analysis Settings object. When you include this criterion, the solver requires fewer iterations to achieve a moderately accurate solution as compared to the Force Convergence criterion. Property options include:
(default)
When set to , the following additional properties become available:
Value: Default value is which is equal to an entry of zero (0).
Tolerance: Default value is 0.5%.
Minimum Reference: Default value is 1 J.
See the Nonlinear Controls for Steady-State, Static, and Transient Analyses section of the Mechanical User’s Guide for descriptions of the these properties.
Note: Like most convergence criteria, all convergence plots include designations where any bisections, converged substeps, converged steps, or remesh points occur.
