The next thing to look at is an un-averaged stress fringe plot. These are created using the Results Definition data form. Select Von Mises stress for the Quantity and Fringe option under Display. Next, un-select the Average button under the display area. Set the Feature Angle to zero (this will make element edges visible). This will result in plots showing the raw element-by-element stress calculation. You will see that the stress fringes do not line up across element boundaries. The more continuous the stresses are across the mesh, the better the solution is.
For MPA solutions (not SPA) you need to look at measure convergence plots. These are crated using the Results Definition data form. Select Measures for Quantity and Graph for Display. These plots will show the measure values from pass-to-pass during the convergence process. The MPA algorithm only compares the last two passes for the percent change. This alone does not mean you have a good solution. You need to look at the shape of the curve. You would like to see an asymptotic convergence curve over several points.
