Performing a stress analysis

When performing a stress analysis, the first solution you get is a coarse estimate of the stresses. This is useful to get a good grip on where the weaknesses of the design are located.

Refinements

In order to get a more accurate estimation, you will have to refine a few times. Refinements are controlled under the Solutions tab (the far right one).

Convergence

When you have more than one solution, the convergence plot will have enough values to show you a graph, but you will need at least three refinement levels in order to make an assumption on the convergence of the problem.
