Reply To: Multiphase Solid Liquid Flow


Dear Ananda,

rho1 is used as the main density in Navier-Stokes lattice and as inlet density in the transport ADE equation. rho0 is 0 and is starting density in the whole volume of the geometry. Density is in both equations in lattice units. In the ADE equation the density can be seen as lattice volume or mass fraction. This is free to choose for You. You can also take 1 as 30% of real volume fraction and then all results of the simulation must be multiplied by 0,3. Transport equation just distributes the given scalar, it is up to You to choose what for physical sense the lattice density must have. In the bifurcation example this is just volume fraction of 1 that is transported further through the geometry.
