GiD user manual : Creating a non-conformal mesh

 NOTE : Non-conformal meshes may be used with some calculating modules, i.e. stamping a plate. Using non-conformal meshes significantly reduces the number of elements in the mesh. This cuts down on computation time.

  • Select View->Mode->Geometry .
  • Select Geometry->Edit->Uncollapse->Surfaces . Select all the surfaces in the model. Press ESC . A sufficient number of lines and points is created so that no surface (of the object) shares lines with any contiguous surface.
  • Select Mesh->Generate Mesh . When the mesh has been generated, a window appears with information about the mesh (Figure 29). The result is a non-conformal mesh composed of far fewer elements than the meshes generated in the previous section: about 4.000 elements instead of the 10.000 needed to generate the conformal mesh.

  • Visualize the result using Mesh->View mesh boundary .

Now each surface is independent of the other surfaces.
