C --*** RENUMB *** (GEN3D) Find the new element and node numbers
|
||
|
|
C -- Written by Amy Gilkey - revised 04/22/88
|
||
|
|
C --
|
||
|
|
C --RENUMB calculates the new node and element numbers and the number
|
||
|
|
C --of nodes/element generated for each node/element. Unless the
|
||
|
|
C --node or element is part of a center block, the number generated
|
||
|
|
C --is simply the number of repetitions. For a center block, the
|
||
|
|
C --elements and nodes are ordered by row and column, and the number
|
||
|
|
C --of repetitions is assigned from the column number. The new node
|
||
|
|
C --number is assigned so that the node and all the nodes it generates
|
||
|
|
C --are grouped together. For example, if the new node number is 20,
|
||
|
|
C --the node it generates in the first translation would be 21. The
|
||
|
|
C --elements are handled the same way.
|
||
|
|
C --
|
||
|
|
C --The output number of nodes and elements are set.
|
||
|
|
C --
|
||
|
|
C --Parameters:
|
||
|
|
C -- A - IN - the dynamic memory base
|
||
|
|
C -- BLKTYP - IN - the element block type
|
||
|
|
C -- NUMELB - IN - the number of elements for each block
|
||
|
|
C -- LINK - IN - the connectivity for the 2D elements, always 4 nodes
|
||
|
|
C -- XN, YN - IN - the nodal coordinates
|
||
|
|
C -- IXEL - OUT - the new index for each element
|
||
|
|
C -- INCEL - OUT - the increment for each element, needed for blocks that
|
||
|
|
C -- become multiple blocks
|
||
|
|
C -- NREL - OUT - the number of new elements generated for each element
|
||
|
|
C -- IELCOL - OUT - the row number for each element, 0 if not needed,
|
||
|
|
C -- needed for single point center, useful for other centers
|
||
|
|
C -- IXNP - OUT - the new index for each node
|
||
|
|
C -- NRNP - OUT - the number of new nodes generated for each node
|
||
|
|
C -- NPCEN - OUT - the node numbers of the center nodes by column and row
|
||
|
|
C -- IELROW - SCRATCH - size = NUMEL
|
||
|
|
C -- IROT - OUT - tracks connectivity rotation to update sset faces
|
||
|
|
C --
|
||
|
|
C --Common Variables:
|
||
|
|
C -- Uses NUMNP, NUMEL of /DBNUMS/
|
||
|
|
C -- Sets NUMNP3, NUMEL3 of /DBNUM3/
|
||
|
|
C -- Uses NNREPL, NEREPL, DIM3, NUMCOL, NUMROW of /PARAMS/
