I need some help…I've done many test but can't find the right way. The simulation I would make is the following:

A container filled with chocolate (first fluid) and from the top I would pour a second fluid (whipped cream) that will fall and collide with liquid chocolate.

I would like to have the possibility to control 2 different solver for the fluids (one for whipped cream and one for chocolate) in order to achieve a more realistic effect of the simulation. At the moment I've done this effect with one solver but i'm not happy.

I hope that someone can help me.

Thank you.
