Convergence Settings
Set convergence criteria for a collection of entities to specify the result type and maximum number of h refinements to reach convergence. Convergence can occur in fewer refinements than requested in the settings dialog box. The resulting Convergence Plot displays:

Static Simulations
- Maximum Number of h Refinements
- Specifies the maximum number of h refinement cycles for convergence. Default is 0.
For values higher than 2, a dialog box displays. Increasing the number of refinements could decrease performance.
Value increment is 1.
If the Stop Criteria is met, the refinements can cease before the maximum number is reached.
- Stop Criteria (%)
- Ceases refinement when the difference between the last two results is less than the specified (%) value. Value increment is 1. The refinement can cease when it reaches the maximum number of refinements, even if Stop Criteria is met.
- h Refinement Threshold (0 to 1)
- Specifies the refinement threshold (between 0 to 1). A zero setting means include all the elements in the set as candidates for refinement. The results are the maximum refinement per cycle. 1 means exclude all elements in the set from refinement, as in no refinement. The default is .75, which means, of the elements with equivalent errors at the top, 25% are subject to refinements. Not applicable to Modal analysis.
Value increment is 0.1.

- Geometry Selections
-
- All Geometry Specifies that all geometry is considered for the convergence criteria
- Include Selected Geometry Specifies that only the items in the list are included as the set in the convergence criteria.
- Exclude Selected Geometry Specifies that the items in the list are excluded from the set in the convergence criteria.
- Bodies Filters the list to display only bodies.
- Faces Filters the list to display only faces
Modal Simulations
- Maximum Number of h Refinements
- Specifies the maximum number of h refinement cycles for convergence. Default is 0.
For values higher than 2, a dialog box displays. Increasing the number of refinements could decrease performance.
- Stop Criteria (%)
- Ceases refinement when the difference between the last two results is less than the specified (%) value.
- Results to Converge
- Frequency Mode Specifies the mode number for results convergence.
Convergence Plot
- The number of refinements required for the solution to converge, if convergence is achieved, or the number of solution steps requested for the required refinements.
- The values associated with each refinement.
The window close button in the upper right corner dismisses the dialog box.
To change the plot results criteria, right-click in any open space within the plot pane. Then, click Plot Options.
