  <p>The physics here is a two-dimensional turbulence calculation
  in a 64x64 psuedospectral model.</P>

  <p>Various tracer models (passive or active) are included.</P>
 
  <p>To view the movies, you need mpeg_play.
  For the individual frames, you need xwud</P>
 
  <p>For the runs with particles, the colored field is the streamfunction.
  The particles are assumed to attract each other: For each particle,
  you comput a vector attracting velocity for all the other particles
  and average it. The attracting velocity depends on the separation as
  u0*(r-r0)/L*exp(-(r-r0)^2/L^2). L=4 and the domain size is 64*0.3</P>
 
  <p>For the tracer runs, the colored field is the tracer and the
  contours are the streamfunction. The case with only a numerical
  filter for stability shows a lot of (I think) spurious structure at
  small scales. The case with a little mixing looks better.</p>
