# gp.flow

Syntax

f := gp.flow(gp)
gp.flow(gp) := f

Get/set the unbalanced flow discharge at a gridpoint. The unit is $$L^3/T$$. This corresponds to the net inflow or outflow at a gridpoint. The summation of such flows along a boundary where the pore pressure is fixed is useful because it can provide a value for the total outflow or inflow for a system.

Returns: f - the unbalanced flow discharge f - the unbalanced flow discharge gp - a zone gridpoint pointer
