C --*** CFV2NV *** (DETOUR) Convert face variable to nodal variable

C --

|
C --CFV2NV converts a face variable to a nodal variable by averaging
|
|
C --the values for all "active" elements containing the node.
|
|
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 -- IELBST - IN - the element block status (>0 if selected)
|
|
C -- ISEVOK - IN - the element block variable truth table;
|
|
C -- variable of block j exists iff ISEVOK(j)
|
|
C -- VARFAC - IN - the face variable values
|
|
C -- DOVN2B - IN/OUT - set IVN2B and IFVCNT iff true; set false
|
|
C -- IVN2B - IN/OUT - the element block for each node for this variable;
|
|
C -- <0 if not in any selected element block
|
|
C -- =0 if in more than one selected element block
|
|
C -- IFVCNT - IN/OUT - the connected face counts for each node
|
|
C -- for this variable
|
|
C -- VARNP - OUT - the nodal variable values
|

|
|
C -- Uses NELBLK of /DBNUMS/
|
