C --*** WRSTEP *** (ALGEBRA) Write database variables for one time step
|
||
|
|
C -- Written by Amy Gilkey - revised 05/18/88
|
||
|
|
C --
|
||
|
|
C --WRSTEP writes the database history, global, nodal, and element variables
|
||
|
|
C --for one time step.
|
||
|
|
C --
|
||
|
|
C --Parameters:
|
||
|
|
C -- NDBOUT - IN - the output database file
|
||
|
|
C -- MAXNE - IN - the VARVAL dimension (max of NUMEL and NUMNP)
|
||
|
|
C -- VARVAL - IN - the output database variables
|
||
|
|
C -- VISELB - IN - true iff element block i is to be written
|
||
|
|
C -- IXNODE - IN - the indices of the output nodes (iff NUMNPO <> NUMNP)
|
||
|
|
C -- IXELB - IN - the cumulative element counts for each element block
|
||
|
|
C -- IXELBO - IN - the cumulative element counts for each output block;
|
||
|
|
C -- IXELEM - IN - the indices of the output elements (iff NUMELO <> NUMEL)
|
||
|
|
C -- ISEVOK - IN - the element block variable truth table;
|
||
|
|
C -- variable i of block j exists iff ISEVOK(j,i)
|
||
|
|
C -- MERR - OUT - error code
|
||
|
|
C --
|
||
|
|
C --Database must be positioned in front of time step upon entry;
|
||
|
|
C --upon exit positioned after time step.
