In both cases I was investigating how mesh fineness affects the deflections and the resulting gap between the thick plates at their corners (in a 1st and 2nd order mesh).
Coarse meshes finish simulations for both 1st and 2nd order meshes.
@DaleKramer: from simulation point of view (not mine, as I do not know anything about FEA) I will beg for more processors. You have > 7 M cells and try simulation on 4 processors…
Solved! Problem is that you have to apply the setting to the subsections separately which is daunting but works like a charm now. Let me know if you need any further assistance with your case.
