I would like to analyse turbulence in ENZO by comparing velocity difference at different scales. To do this I would like to calculate the velocity difference between each cell and cells a set distance bracket away, square, sum over all cells, and square root to get a turbulent velocity at that length scale. I would the like to do that for many different length scales to form a graph of turbulent velocity against length scale.
This actually shouldn't be too difficult using a kdtree... I'll explain more in a bit, I'm going to take a quick whack at sketching something up...
