[Gmsh] Question Gmsh in FreeCAD

[Takdanai Tapsuwan]

Dear Sirs,

I am doing right now my bachelor-thesis in topic FE-Simulation for a cast componet. Now, I did my componet meshing in FreeCAD and I would like to ask you some questions:

1. What did the Gmsh in FreeCAD do? Is it Tria3 (linear) or Tria6 (quad) selected?
2. What's the different between meshing by shape and meshing by 3D?

Many thanks in advance

Best regards
