C --*** MSLINS *** (MESH) Create line set from surface faces

C --
|

|
C --MSLINS creates a line set of all lines making up the surface faces.
|
||
|
|
C --The lines are classified and sorted into the following parts:
|
||
|
|
C -- -1) Edge
|
||
|
|
C -- 0) Element block boundary
|
||
|
|
C -- n) Interior within element block 'n'
|
||
|
|
C --
|
||
|
|
C --Parameters:
|
||
|
|
C -- A - IN - the dynamic memory base array
|
||
|
|
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 surface faces
|
||
|
|
C -- IF2EL - IN - the element number of each face
|
||
|
|
C -- LENL - OUT - the cumulative line counts by element block
|
||
|
|
C -- KLNSET - OUT - the dynamic memory index of sorted line set,
|
||
|
|
C -- for surface faces only
