INOUT_FLOW_MOVIE
Flow Animation for the INOUT Cell

INOUT_FLOW_MOVIE is a MATLAB program which creates an animation of the velocity solutions to a time-dependent incompressible parameterized flow problem in a cell with inflow and outflow.

The "INOUT" region is contained in the unit square, [0,1] x [0,1]. There is an inlet on the left side, from [0,0] to [0,0.2], and an outlet on the right side, from [1,0.8] to [1.0,1.0].

Source Code:

• inout_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.
• inout_flow_png.m, saves the individual frames as PNG files.
