Hi Foamers,

This small tool I wrote calculates the correlation dimension of the distributions of lagrangian particles, as introduced in Tang et al: Self‐organizing particle dispersion mechanism in a plane wake (1992). This is useful to determine if the particles are nicely distributed or if they are agglomerating in lines, planes, etc. Basically you get a value which describes a kind of "dimensionality" of the distribution. A value of 3 means that particles are more or less evenly distributed in all 3 dimensions. 1 would mean that they are forming some kind of line.

Please feel free to use it or to post bugs, hints for improvement, ...

Update: As the tool calculates the distances from all particles to all others it needs lots of memory if there are many particles. For example I tried it with 80k particles which caused the program to use ~45GB of RAM.
