Hello,

I'm trying to simulate a single bubble shape oscillation and I needed help in modelling it.

I created the grid using Gambit. The problem I'm facing is that the bubble interface is not being exported.

I have a made a square domain. At the center of the domain I've created a edge who's shape is that of the bubble. I meshed the whole square domain and then tried to split the mesh along the bubble interface. I'm getting some errors saying that the split is unsuccessful.

When I tried by creating two faces but meshed only the square domain, the bubble interface doesn't get exported because the other face is not meshed. I do not want to define two separate faces which are non-intersecting and mesh them, as that will not result in a structured mesh.

What I need is that the whole domain must be meshed as shown in the attached figure http://imgur.com/0lFY5jD. Then split the mesh along the bubble boundary so that it allows me to specify two different zones.

Please Help!
