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.

CAVITY_FLOW_MOVIE is available in a MATLAB version.
CAVITY_FLOW, a dataset directory which contains 500 solutions of the driven cavity flow problem.
CAVITY_FLOW_DISPLAY, a MATLAB program which displays a single solution of the cavity flow problem.
FILE_NAME_SEQUENCE, a MATLAB program which demonstrates four ways to generate a sequence of filenames.
MP4, a data directory which contains the animation of the driven cavity data created by this routine.
PEAK_MOVIE, a MATLAB program which creates the pieces of an animation, one frame at a time. Each frame is independently created and saved as a JPEG file.
VELOCITY_ARROWS_GRID, a MATLAB program which reads files of node and velocity data, and, using interpolation, creates a vector plot with arrows place on a uniform grid of the user's specification.
