In previous versions of FreeCAD, Netgen was the default mesher. For it to work with the FEM Workbench, FreeCAD had to be linked against the Netgen libraries at compile time. As FreeCAD transitioned from OCE 0.17 to OCCT 7.1, Netgen 4.9.13 failed to link against this version of OCCT, so it was decided to drop Netgen support in the FEM Workbench (the Netgen button was removed). Nevertheless, shortly afterwards some users reported success in patching Netgen 5.3.1, so that it worked with OCCT 7.x and FreeCAD.
