First of all I’m very glad the fluid particle core is now committed thanks to Jahka and also he has fixed the moving emitter object bug, but aside of that there’s no other bug. Unstable simulations are not bugs but limitations of the current solver (and actually limitations of the SPH theory, it is not unconditionally stable)
In Realflow you could get very easy unstable sims too 😉
The videos I have recorded explicitly say that where form a previous patch version, lots of things have changed after that.. And I’m working now on a proper and official documentation and later on improving stability.
If someone have problematic setups try to send it at email@example.com
but an important advice is that with fluid particle colliders should have friction and damping around 0.5 or higher values!
