Mixable vs unmixable multiphase flow

Mixability concerns surface tension : in the unmixable fluid, surface tension concerns only particles of the same species. Whereas in a fully mixable fluid, surface tension occurs between any particle, no matter what species it is. In this video, 3 fluids with ratio 1:0.5:. Following is the video log for 1 simulation, this video is the result of 2 simulations. ~~~~~~~~~~~~~ | VIDEO LOG | ~~~~~~~~~~~~~ Number of particles : 21635 Domain size : x Time step : Time scale : Particle spacing : % Interaction radius : 300% Gravity : Display target : density Simulated time : Simulation time : 6m 52s Video time : 1m 0s Simulation factor : Frame per seconds : Seconds per frame :
