Hi everybody,

Does anyone have any experience doing enginge simulations with topological changes, replacing the sliding interface by a ggi? The reason I am trying to do this is, I am having some troubles with the sliding interface, and it seemed to me that the ggi was a bit more robust. I got it working for a 3D case, but just setting up the valve bottom, so there is nothing above the valve bottom, as if it were a wall moving down. Now I am trying a 2D case with the complete valve, it runs well for one iteration, and on the second one it crashes and says:

--> FOAM FATAL ERROR:
Problem with patch-to zone addressing: some patch faces not found in interpolation zone

From function void ggiPolyPatch::calcZoneAddressing() const
in file meshes/polyMesh/polyPatches/constraint/ggi/ggiPolyPatch.C at line 77.

FOAM aborting

Has any one faced something like this? is it even possible?

best regards,
abm
