cavity_flow_display

cavity_flow_display, an Octave code which displays the velocity field at a single timestep, presumably from a series of solutions of a time-dependent incompressible flow 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.
