FEM MeshClear

Description
Enables the user to delete the mesh from the FreeCAD file. The meshing information, Netgen/Gmesh parameters, mesh regions, mesh groups and mesh boundary layer remain in the Model Tree, which means the mesh can be reproduced later. The main use of this function is to lighten the FreeCAD file, either to improve performance when using FreeCAD, to save disk space or enable easy transfer of files without losing meshing data.

Usage
There are several ways to execute this function:


 * 1) Select the mesh object in the Model Tree [[Image:FEM_MeshGmshFromShape.svg|32px]] FEM mesh from shape by Gmsh.
 * 2) Select the  option from the menu.

Alternatively:


 * 1) Right click on the mesh object in the Model Tree [[Image:FEM_MeshGmshFromShape.svg|32px]] FEM mesh from shape by Gmsh.
 * 2) Select the [[Image:FEM_MeshClear.svg|32px]] Clear FEM mesh.

The objects in the Model Tree are maintained because they represent the meshing data, but the mesh is now cleared from the FreeCAD file.
