In order to create a FEM Mesh, FreeCAD uses Gmsh as the default mesher. Depending or your operating system and your FreeCAD installation Gmsh is bundled with the FreeCAD installation binaries or not. If it is not bundled you can install it separately from FreeCAD and then use the menu Edit → Preferences → FEM → Gmsh to set the path to the gmsh.exe.
