The convergence loop log also lists convergence indicators at each pass. These percentages are based on changes between the current pass and the preceding pass, and provide an indication of the accuracy of the results.

If you intentionally define an analysis that requires only a single p-loop pass by setting the minimum and maximum polynomial orders to the same value, Creo Simulate sets the convergence indicators to 100% and warns that convergence has not been checked, because there is no preceding pass with which to compare.

The Structure engine calculates the following convergence indicators:
