Is it possible to define a mass transfer between the two phases of air and water at those points where the volume fraction is equal to 0.5? The difficulty of the problem here is that the points where the volume fraction is 0.5 are variable and not fixed. In COMSOL, to define a flux, the boundary must be constant. Thank you for your help.
Hi, I need to simulate a droplet falling to a solid surface and moving on the surface what kind of phyisics interface should I use level set method or two phase flow method.
@@engineeringtraining2024 should a add the solid surface on the level set domain or I need to use structural mehcanics and add the solid their and then couple?
Can you explain how to simulate a 2phase flow (water and air) through unsaturated soil by using two phase darcys law?

Can you explain why didnt you assign both materials to respective domains? What is the benefit of this?
And a second question, what drives this flow?
It uses the mix property of the material, as well as different densities as driving forces.
what version of this comsol ? i want to make flow fluid in the pipe, newbie
V6
can you do a 3d SIMULATION video where we can track the fluid deposition from a nozzle on a substrate using phase field (two phase)method? please
Ok.
