What makes this solver more suitable than calculix solver?
The benefit of FrontISTR is, that the solver can handle very huge meshes.
On work I mostly use netgen, gmsh often needs mesh-refinement zones.
My experience in the last weeks was, that you can mesh complete assemblies
with hundreds of thousands of cells. In the example below (the beam with the two plates)
you simply start netgen, max cell size 10 mm, fine mesh, run FrontISTR, work done.
OK, that is the brute force method and not very elegant.
But for me it saves time (in our company there is a big hourglass on every desk...
For smaller modells up to 100000 cells I still use CCX. There is no runtime difference,
from a practical point of view.
