Convergence Method

Convergence gives you an idea of how accurate your results are. If your analysis does not reach convergence during a design study, the results may not have the desired accuracy. In this case, you need to modify your model.

Select one of these convergence methods for Creo Simulate to use when it runs your analysis:

• Multi-Pass Adaptive—Calculates results at increasing polynomial orders until convergence criteria are satisfied.

• Single-Pass Adaptive—Runs a first pass at a polynomial order of 3 and determines a local estimate of stress error. Using this error estimate, Creo Simulate determines a new p-order distribution and performs a final pass.

• Quick Check (No Convergence)—Performs a single pass at a uniform polynomial order of 3. You can use this method to verify that you have defined your analysis correctly.

This table summarizes which methods are available for different analysis and model types:

Analysis Types	Multi-Pass Adaptive	Single-Pass Adaptive	Quick Check
linear static, modal	available	available only for 3D models or plane strain and axisymmetric models with 2D solids or plane stress models with 2D shells.	available
