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.
rmpoint/pset, get, pset1
mark all the nodes in pset1 for
removal. Remove elements all of whose vertices are members of pset1.
