C --FACELB makes up a list of faces for all faces in an element block.
|
|
C --All matching faces within the block are combined.
|
|
C --
|
|
C --Parameters:
|
|
C -- IELB - IN - the element block number
|
|
C -- LENE - IN - the cumulative element counts by element block
|
|
C -- NLNKE - IN - the number of nodes per element
|
|
C -- LINKE - IN - the connectivity for all elements
|
|
C -- NLNKSC - IN - the number of nodes per face
|
|
C -- LINKSC - IN/OUT - the connectivity for all faces (this block only)
|
|
C -- IF2ESC - IN/OUT - the element number(s) of each face in LINKSC
|
|
C -- MAXNPF - IN - the maximum length of the NPFS entry
|
|
C -- NPFS - SCRATCH - the list of unmatched faces containing a node;
|
|
C -- (0,i) = the length of the list
|
|
C -- NFACES - OUT - the number of unique faces in this element block
