Reaflow, Dyverso, Granular, 10.2 M particles. 2 h 20min. on 2*Xeon 2630 v4 (GPU simulation din't work, I guess it's about Filter bug or sort of) I used Jittering (set to 1.0) of a Fill Emitter to create uneven look of particles (first domain), but it turned out that Particles fly away at the very first moment. Interpenetration (of the first domain) set to 0 fixed the problem, But some particles of the second domain (filter move) come through the particles of the first domain.
