Hi
There are two aspects to my problem.
One is a phase evolution within a defined boundary. I have been successful with this part. (It is very similar to simulating two non-miscible liquids separating out.)
The second aspect is that the same phase evolution now needs to happen within a boundary which changes shape with time. The 'shape change' is a physical phenomenon and the precise change of shape is well defined. The mass is conserved through out.
My questions are:
1. How to get the boundaries (which are defined in comsol as 'walls' ) to deform and change shape in a defined way. To get started, is it possible to change a square domain into a circular domian?
2. At the same time, while this boundary shape change is happening, I want the phase evolution to happen and I want the internal mesh to adapt to the new boundary shape at each time step. How to couple them together?
