Particles Adaptive Subframes

Sorry for being so long between posts , anyway, time for some cool stuff, especially GSoC shaping up to be a good one :)

Recently there has been a little development is the realm of particles, particularly Fluid (SPH) particles, anyone who has used fluid particles have all encontered the problem of exploding fluids, where wdroplets would just explode for no real reason, and the solution to this was increase the subframes, which rarly if ever work and add on a huge amount of simtime.

Now there is an option to apply the amount of subframes dynamiclly and mathermaticlly, using the velocity of neighours and distance, and all these fancy calculations, to give very nice and stable simlation with little or no cost in time.

As usual pictures speak loader then words so below is a comparison vid, with resulting sims and time to simulate.
