Nonlinear driven cavity with multigrid in 2d.<BR> <BR>
The 2D driven cavity problem is solved in a velocity-vorticity formulation.<BR>
The flow can be driven with the lid or with bouyancy or both:<BR>
-lidvelocity &ltlid&gt, where &ltlid&gt = dimensionless velocity of lid<BR>
-grashof &ltgr&gt, where &ltgr&gt = dimensionless temperature gradent<BR>
