C --RDSTEP reads the input database variables for one time step and
|
||
|
|
C --stores the ones used in the equations in array VARVAL.

|
|
C --Parameters:
|
||
|
|
C -- ISTEP - IN - the time step number
|
||
|
|
C -- TIME - IN - the time step time
|
||
|
|
C -- NUMELB - IN - the number of elements per block
|
||
|
|
C -- ISEVOK - IN - the element block variable truth table;
|
||
|
|
C -- variable i of block j exists iff ISEVOK(j,i)
|
||
|
|
C -- MAXNE - IN - the VARVAL dimension
|
||
|
|
C -- VARVAL - OUT - the input data needed
|
||
|
|
C -- MERR - OUT - error flag
