The new Z88 settings and their default values
The Z88 solver is now fully usable. You can specify the solver method and change the memory settings. The new default values allow you to perform also complex simulations directly.

Result of a linear buckling analysis.
Click on the image to see the animation.
It is now possible to perform buckling analyses using the Calculix solver. Pull request #4379

Effect of Mesh Size From Curvature; left: set to 12, right: deactivated
There is a new property for the Gmsh mesher. The number of mesh elements per times the radius of the curvature can be specified. The default is 12 and to get a finer mesh at small corners or holes, this value can be increased for better results. This feature requires Gmsh 4.8 or newer.

Forum discussion, Pull request #4596


Effect of the recombination algorithm; left: using Simple, right: using Simple full-quad
FreeCAD now allows to select an algorithm as well as 3D mesh recombination for the Gmsh mesher. For more details about mesh element recombination see FEM MeshGmshFromShape.
