dynamic mesh is cool
 

Hello OpenFoamer,

I have been playing with dynamicMesh for fun.
However I'm now stuck on a little problem. I'm trying to model a "real "dam break ( with collapsing wall-rather than just a column of water).
I got it to work , if the walls are vertical .

However sure enough if I put some slope , the top of the wall will start to "sink in" between the sloping wall after a bit of time.

I guess my question is:
Is there a simple way of forcing a face ( heres the dam slope) to stay "attached" to a moving face ( top of dam) ?
I have attached the case, in case anyone is interested in helping.
Cheers,

Olivier
