C --
|

|
C --ZMNPS compresses the nodal point sets by removing deleted nodes.
|
||
|
|
C --Assumes that the nodes are already renumbered and ordered.

C --
|
||
|
|
C --Parameters:
|
||
|
|
C -- NUMNPS - IN - the number of nodal point sets
|
||
|
|
C -- LNPSNL - IN/OUT - the length of the nodal point sets node list
|
||
|
|
C -- LNPSDF - IN/OUT - the length of the dist.fact. node list
|
||
|
|
C -- IDNPS - IN - the nodal point set ID for each set
|
||
|
|
C -- NNNPS - IN/OUT - the number of nodes for each set
|
||
|
|
C -- IXNNPS - IN/OUT - the index of the first node for each set
|
||
|
|
C -- LTNNPS - IN/OUT - the nodes for all sets
|
||
|
|
C -- FACNPS - IN/OUT - the distribution factors for all sets
