Hi,
I am trying to set up a 3D case of an engine using sonicTurbDyMEngineFoam, and the simpleEngineTopoFvMesh library, but it seems to have troubles with the sliding interface. In the 2D model done with blockMesh that I have, there is no problems, but of course, I declare the nodes corresponding to the valveCurtain on the port and cylinder side twice. In my 3D case, I can't do this since I can't use blockMesh so I do different meshes, one on the cylinder side and one on the port side. Of course there is no 100% correspondence in the nodes of one side with the ones in the other, but there shouldn't be right? After all it is an interface. So anyway when I try to move the mesh (I use moveDyMEngineMesh for that, I get the following error:

--> FOAM FATAL ERROR:

FOAM aborting

any ideas? I am really stuck. Any help would be greatly appreciated.
