I have been experimenting with SPH recently and presently have a bake going. However the decision of classical or double density confuses me.
In 0 gravity , classical explodes into the expanse in clumped blobs (not a desired affect) Whereas double density sort of grows as a single blob around the emitter (also not what i expected)
I also took note that the classical solver was greatly slower than the double density version; although i have no benchmarks to back it up.
Does anyone else have something they would like to state that might help me?
