Deleting Elements

You can delete poor quality elements from a mesh.

Before you begin: Create a surface mesh in the finite element model representation and open it in either the Mesh Editor or the Surface Mesher.
Note: Mesh editing operations that modify the mesh topology (deletes or adds nodes or elements) can result in a loss of the association between the mesh and the geometry. In general, when editing in the Surface Mesher, association is maintained; when editing in the Mesh Editor, association is not maintained.
