TCELL_FLOW_MOVIE
Animation of Flow Solutions in a T-Cell

TCELL_FLOW_MOVIE is a MATLAB program which animates the pressure or velocity data in solutions of the incompressible parameterized flow problem in a 2D T-cell.

Related Data and Programs:

FILE_NAME_SEQUENCE, is a MATLAB program which demonstrates four ways to generate a sequence of filenames.

MP4, a data directory which contains examples of MP4 files, the MPEG-4 movie file format for 2D animation;

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.

TCELL, a FORTRAN77 program which solves the Navier Stokes fluid flow equations in a 2D T-shaped region.

TCELL_FLOW, a dataset directory which contains 500 time steps of Navier-Stokes flow in a 2D T-shaped region.

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.

Source Code:

• tcell_flow_jpeg.m, is a MATLAB M script file which reads EACH velocity file, displaying the normalized or unnormalized field, and making a JPEG file of each image for assembly into an animation.
• tcell_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.
• tcell_flow_png.m, is a MATLAB M script file which reads EACH velocity file, displaying the normalized or unnormalized field, and making a PNG file of each image for assembly into an animation.
• tcell_flow_snapshot.m, is a MATLAB M script file which reads ONE velocity file, displaying the normalized or unnormalized field.

Examples and Tests:

• xy.txt, the XY coordinates associated with the nodes.
• elements.txt, a grouping of the nodes into 6 node quadratic finite elements.
• steady.txt, the steady state velocity field.
