Există modalități diferite de a crea o plasă de discretizare MEF în FreeCAD:
 * Netgen FEM instrument Mesh FreeCAD MeshNetgenFromShape utilizând GUI sau Python
 * FreeCAD FEM instrument de plasă GMSH MeshGmshFromShape utilizând GUI sau Python
 * Python înseamnă a face direct FEM Mesh de mână
 * Importați o plasă FEM

Les objets créés dans PartDesign et Part sont pris en charge, ainsi que de simples copies de ces corps. Deux mailleurs sont disponibles pour l'utilisateur: Netgen et GMSH. Netgen est inclus dans FreeCAD. Pour GMSH, un binaire externe doit être installé. Voir 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.
