Dear Foamers,

I was struggling with a moving mesh case, I was hoping that someone can give me a hint.

The case consist of a hollow rectangular in the middle of the domain which will shrink in time. In the first attempt, I had different patches for the different edges of the rectangular. When the mesh shrinks, the edges intersect and the solution stops. I fixed the problem by combining all the edges to one patch. Now after some times, one or more meshes have zero edge size and the solution stops.

Any idea how to tackle the problem? Should I consider my case as a "topoChange" or the DynamicMesh can handle that?

I'm using OF4.1.

Thanks
