RMPOINT

Removes nodes or marks nodes for removal points or removes elements from a mesh.   The first option sets the node type flag  [itp=ifitpdud (21)] to indicate that the set of nodes are treated as invisible, but does not actually remove the nodes.  Elements will also be removed.  If  inclusive is specified, any element containing a marked node will be removed.  If  exclusive is specified (default), any element containing a retained node is retained.  The second option, compress, removes the invisible nodes (i.e. those nodes whose itp1 value is 21) from the data structure and material-wise resequences all remaining nodes.  The third option, zero_volume, will remove elements whose volumes are less than or equal to the specified threshold.  The fourth option, element, will remove all marked elements from the mesh.  Marked elements have a negative value for the first entry in the itet vertex list.  The fifth option will remove a specified list of elements from the mesh.  The sixth option will remove elements that are specified in a named element set from the mesh. The seventh option, womesh will delete stray nodes that are not connected to any element and that are not parent nodes.
