So by your quotes, we have three diffrent "categories" of engines. Problem is I went to the tokamak, newton, and ode sites and can't for the life of me find ANY information that addresses the above. Where are you getting this info from? I have not reason to doubt the above, I just can't seem to find ANYTHING like the above in any of the sources I'm looking at. Is it books or mags or what? I'd be interested in comparing the "guts" of all these free (and mostly open source) engines. I'm not looking forward to actually having to decipher this info from looking at the code....brrrrrr.....:(
I guess I'm looking for equations or something less code related and more as to HOW THEY DO THE PHYSICS and not just estimates. Saying that ODE uses an O(n^3) solver says nothing to me without some context or proof of where this comes from.
