C --MAKSUR calculates the nodes-on-surface indicator (NPSURF).

C --
|
|
C --Parameters:
|
|
C -- LENF - IN - the cumulative face counts by element block
|
|
C -- NLNKF - IN - the number of nodes per face
|
|
C -- LINKF - IN - the connectivity for all faces
|
|
C -- DODEAD - IN - add in dead nodes from IDN2B iff true
|
|
C -- IDN2B - IN - the element block for each dead node; dead if >= 0
|
|
C -- NPSURF - OUT - the node numbers of the surface nodes
|

C --Common Variables:
|
|
C -- Uses NDIM, NELBLK of /DBNUMS/
|
|
C -- Sets NNPSUR, NUMNPF of /D3NUMS/
