smooth interface with VOF models

I am simulating bubble collapse close to a wall. when I want to patch pressure and temperature to the inside of bubble, I realize that the bubble interface is sharp (although I have a fine mesh). Does anybody know what can I do to smooth the interface? I read somewhere in other posts that I can use TUI command: rpsetvar 'patch/vof? #t

I don't know where to use this command. Can anybody help me please.

Are you using the vof explicit method with geo-recronstuction?, because, if you are using this method, i think your mesh is not fine enough.

Yes I am using that method. But I have even refined the mesh near and inside the bubble (around 0.5 million nodes) but still can get smooth pressure contours. any idea how fine should I make the mesh?
