From FreeCAD Documentation

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