  • using distributed arrays; Transient nonlinear driven cavity in 2d.

    The 2D driven cavity problem is solved in a velocity-vorticity formulation.
    The flow can be driven with the lid or with bouyancy or both:
    -lidvelocity <lid>, where <lid> = dimensionless velocity of lid
    -grashof <gr>, where <gr> = dimensionless temperature gradent
    -prandtl <pr>, where <pr> = dimensionless thermal/momentum diffusity ratio
    -contours : draw contour plots of solution
