CAVITY_FLOW_MOVIE
Driven Cavity Flow Animation

CAVITY_FLOW_MOVIE is a set of routines for creating 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.

CAVITY_FLOW is a dataset directory which contains 500 solutions of the driven cavity flow problem.

CAVITY_FLOW_DISPLAY is a MATLAB program which displays a single solution of the cavity flow problem.

FREE_FEM_NAVIER_STOKES is a MATLAB program for solving the steady incompressible Navier Stokes equations on an arbitrary triangulated region, using the finite element method.

MP4 is a data directory which contains the animation of the driven cavity data created by this routine.

VELOCITY_ARROWS_GRID is 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.

Source Code:

• 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.
• 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.
• file_name_inc.m, generates the next filename in a series.
• thin_index.m, is a MATLAB M file used by CAVITY_FLOW_MOVIE, which "thins out" the data. Otherwise, there are too many little arrows to see anything.
