Hi all,

Using pressure acoustics module in COMSOL, I’m modeling the acoustic pressure in two domains: air and liquid droplet, where acoustic waves move from air to the liquid droplet. The air domain has the rectangle shape and the droplet domain is drawn using interpolation curve. Now, I wan to define a different continuity condition at the interface between two domains (i.e., with an extra pressure term to the pressure outside) instead of using the auto-enforced continuity condition of COMSOL.

Is there anyway that I can have access to the continuity equation and add an extra term or I have to add a weak form approach?
