Adjust flow volume at end of time step to keep flow rate fixed by adding an appropriate multiple of the linear solution to the Stokes problem arising from a unit forcing in the X-direction. This assumes that the flow rate in the X-direction is to be fixed (as opposed to Y- or Z-) and that the periodic boundary conditions in the X-direction occur at the extreme left and right ends of the mesh.
