Создать FEM Mesh
Существуют различные возможности для создания FEM Mesh во FreeCAD:
 * Инструмент Netgen для сетки FreeCAD FEM MeshNetgenFromShape с использованием графического интерфейса или Python
 * Инструмент GMSH для сетки FreeCAD FEM MeshGmshFromShape с использованием графического интерфейса или Python
 * Python напрямую означает создание сетки FEM вручную
 * Импорт сетки FEM

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. For GMSH an external binary needs to be installed. Refer to FEM Install

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.

General
More informations about the FEM element types and their data structure inside FreeCAD can be find on FEM Element Types.
