Minimum number of passes
This is the minimum number of passes which will be performed during the mesh adaption, even if the results do not change significantly. Sometimes the adaptive mesh refinement needs a couple of passes to figure out the location of the most important regions. Thus it might happen that the results change only marginally during the first few passes but afterwards change in order to converge to the final solution.
Maximum number of passes
This setting determines the maximum number of passes to be performed for the mesh adaption, even if the results have not sufficiently converged so far. This setting is useful to limit the total calculation time to reasonable amounts.
Stopping criterion
If the relative deviation of the energy between two passes is smaller than the error limit the mesh adaptation will terminate.
Refinement percentage
This setting determines, how many percents of mesh tetrahedra are allowed to be subdivided during each adaptation step.
When this option is checked, new nodes that are generated on the surface mesh during the mesh adaption will be projected to the original geometry, so that the approximation of curved surfaces is improved after each adaptation step.
If this option is disabled, the geometry will be approximated by the initial mesh. The geometric discretization error produced by this approximation will therefore not decrease, but the adaptation process might be faster.
Note: If the initial mesh is very coarse and does not resolve the geometry adequately, the snapping may fail locally. A warning will be printed in this case. To prevent this you should consider using a finer mesh, for example by increasing the initial curvature refinement.
