No changes in volume of fluid for Condensation with level set

Please login with a confirmed email address before reporting spam

Dear all,

I am going to simulate the droplet condensation (from vapor to liquid) with the latest version of COMSOL. To do that, I think I need the Laminar Flow(spf), Level Set(ls), and Heat Transfer in Fluids (ht) (with phase change activated) physics to do my simulation. In addition, I only used the Two-Phase Flow, Level Set 1 (tpf1) for Multiphysics coupling due to the fact that all fluid properties are constant. However, when I set up and run my simulation, I understood that the volume of fluid does not change during the simulation time. I would be wondering if you could guide me on this issue.

Kind regards, Nahid
