convective_rolls_movie

convective_rolls_movie, a FreeFem++ code which calculates the convective rolling behavior of a fluid being heated from below, saves each time step as a snapshot, and writes the resulting data to files, using the ffmatlib() interface, for subsequent animation by MATLAB or Octave.
