No matter how we do it, this is going to be a huge hit on speed. Diffusion is a major, major issue. So much so I've considered at times not letting things diffuse at all.
I can't know for sure till I actually have code that does it, but the one psuedo-egrid PY made a while ago wasn't all that good at diffusing... It only did it every like 10 cycles or whatever, otherwise it was too slow.
it explained the math nums
Then why the Hell didn't you post a linky? :lol:
