CAVITY_FLOW_MOVIE
Driven Cavity Flow Animation


CAVITY_FLOW_MOVIE is a MATLAB program which produces an animation of the velocity solutions to a time-dependent incompressible parameterized flow problem in a 2D driven cavity.

The "CAVITY" region is the unit square, [0,1]x[0,1], open on the top, along which a tangential flow is specified, with walls along the sides and bottom.

An evenly spaced grid of 41x41 = 1,681 nodes, is used. These nodes are organized into 800 6-node triangular elements which are quadratic in velocity and linear in pressure.
