• I can understand that kind of frustration. I'll try to get some way to save or preview the results for version 2. This will become more important as more non-linear features are added.

• Hello jvrajadell In Static 3D, the convergence tolerance is only used when it does an iterative solution, which is currently only when compression-only supports are present. Even in that case, the default of 0 really means 10^-11 which is often ade…

• I agree layers should map to components. This will be added in version 2.

• The 2nd and 3rd pictures are a great graphic example of the iterations being incomplete! You can also turn on the constraint symbols with the glasses button in the tool bar to see which nodes ended up in compression (red) and which were released (g…

• The convergence test is done on all the nodes, including those not included in the contact. Typically the error decrease gradually for several iterations then rapidly drops to effectively zero (10^-12 or so) as all contacts end up in their final co…

• Hello Inquisitor The tolerance value is roughly the relative error in the displacements of all nodes. The convergence test with compression only support uses a displacement convergence criterion where it is considered to be converged when ||delta …
