- * if the mesh is computed on a geometry, then "Clear Mesh Data" removes all elements and nodes.
- * if the mesh is not based on a geometry (imported, compound, created from scratch etc.), then "Clear Mesh Data" removes only the elements and nodes computed by algorithms. If no such elements or nodes have been created, can remove nothing.
