karman_vortex

karman_vortex, a FreeFem++ code which calculates the heat transfer occurring in a von Karman vortex street, and writes the resulting data to files, using the ffmatlib() interface, for subsequent graphics processing by MATLAB or Octave.

Source Code:

• karman_vortex.edp, the FreeFem++ script;
• karman_vortex.sh, a BASH script to run the example;
• karman_vortex.txt, the output file;

• ffmatlib.idp, the ffmatlib include file;

• karman_vortex_mh.txt
• karman_vortex.msh
• karman_vortex_xh.txt

The program also creates several hundred data files, containing pressure, temperature, and vorticity information. There are too many files to post on this web site. However, the first set of data is in:

• karman_vortex_pressure_10000.txt
• karman_vortex_temperature_10000.txt
• karman_vortex_vorticity_10000.txt
