Turbulent 3d fields and bnlib-1.3

I've uploaded a new version the "bnlib" library that amongst other items contains the code to generate very large simulations of turbulent fields. The library can be downloaded at:

An illustration of the sorts of effects you can investigate with such
fields here is a slide from a presentation I gave a while back. You
can get the whole presentation at
