cyclicAMI for non matching geometry?
Hello Foamers
If I am not mistaken cyclicAMI can be used to make two independently meshed and moving areas interact with each other. (As seen in the ship's propeller tutorial) My question: Is it possible to connect two meshes which do not match geometrically? E.g. consider two boxes on top of each other. The upper one like three times the size of the lower one and sliding on top of it. Any help/comment/discussion would be greatly appreciated. Best, Thomas |
PS: A competent 'no' would also be a valuable answer...

It is not possible to do currently, maybe you should try 1.6-ext, but I'm not familiar with the features of that code. I had a simulation where only a half cell was non-overlapped with the other side, and the simulation stopped. Hopefully, OpenCFD will improve this very soon. Best, Attila |
You could try the "stitchMesh" tool to connect the grids.

Thank you very much, Attila and Hannes!
So it is not possible to move the meshes relative to each other. :-( Is there a way to define the translation of the boundaries and 'remesh' the entire mesh if neccessary? I think mesh deformation only will not be sufficient in my case because i need an obstacle to be sliding over the ground and then hovering over a channel and continue sliding on the other side's ground.

Hello,
I haven't used it myself, but there should be the sliding mesh interface. stitchMesh is essentially a frontend for this machinery but I think it can be used standalone as well. Regards, Hannes |
