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.

Source Code:

• cavity_flow_jpeg.m, is a MATLAB M script file which reads EACH velocity file, displaying the normalized or unnormalized field, and making a JPEG image, for later assembly into an animation.
• cavity_flow_movie.m, is a MATLAB M script file which can read the XY coordinate file and all the time dependent velocity files, and create an animation. It displays either the velocity or direction field, depending on the internal value of the logical parameter normalized. To keep this script happy, the "#" comment lines were removed from the XY file.
• cavity_flow_png.m, is a MATLAB M script file which reads EACH velocity file, displaying the normalized or unnormalized field, and making a PNG image, for later assembly into an animation.
