There are different possibilities to create a FEM Mesh in FreeCAD:
 * The Gui tool Fem MeshFromShape
 * The Gui tool by Python
 * Python directly means make the FEM Mesh by Hand
 * Import a FEM Mesh

Objects created in PartDesign and Part are supported, as well as simple copies of those bodies. There are two meshers available to the user: Netgen and GMSH. Netgen is included in FreeCAD. Refer to FEM Install For FEM Mesh generation by GMSH user psicofil has provided a GMSHMesh Macro.

FEM Mesh Elements in FreeCAD
FreeCAD supports various element types. There is an external blog link which explains about the differences and when to use which element type: https://www.comsol.com/blogs/meshing-your-geometry-various-element-types/

"ni" means the element type is not implemented in FreeCAD but the format would support it. "-" means the format specification does not support this element type, thus FreeCAD can not support it. "?" it is not known if the format supports this element type.
