1) Can you please provide more information or screenshot of geometry?
Here is my computational domain. There is an inlet on the lower surface, from where phase 2 is extruded into the model domain, the outlet is the upper surface (blue), from where phase 1 exits the domain to guarantee the incompressibility condition.
2) What is volume fraction of phase2?
phase2 is the lava Volume of fraction = 1
phase1 is the air Volume of fraction = 0
3) Please share the details of vof model and model use for phase interaction?
VOF model, implicite, implicite body force,Interface modelling Sharp + interfacial Anti-diffusion. I dont consider phase interaction.
3) How you patch phase 2 after initialization?
I suppose that at the initial time the model domain is filled by air(phase 1), hence there is no phase 2 in the model domain.
Thank you very much for your help!
