GC CARD
Required
DIFFERENT THAN other TABS CONTINUITY
The GC-card dimensions are controlled by program PARAMETER variables MCC and MCCN. Flow
continuity can be calculated at up to MCC lines across part or all of the grid with up to MCCN corner nodes per line.
Prescribe the boundary line first since that line is used in calculating the percents displayed on all subsequent lines.
Code corner nodes only. Code all lines in the same direction; otherwise sign changes will occur in the printout. In
general, code left to right when facing downstream. The first list should be the inflow boundary because is assumed
to be 100%.

Line(J,K)

List of nodes which define the line segments across which the total
flow is to be computed for continuity line checking.
N
End of list
-1
Node number of -1 is required to mark the end of a line.
NOTE: If a continuation line is necessary, start the next corner node in field 1 of the next GC card. These lines may
also be used for automatic generation of boundary conditions.
