Question Cyclic boundary with a rotational and translational transform

Hello Everybody,

i have a question due to the cyclic boundary condition. I want to combine the transform option: translational and rotational. But if i wirte it together in one file (blockMesh.dict or createPatch.dict) Openfoam only read the last command. My back patch is shifted in X and Y direction. Does OpenFoam have any command to match my front and back patch with a rotational transform and a translational transform?

Many thanks in advance for your support!

Question Combine rotation + translation cyclic boundaries

Hi all,

I am facing the same issue.

I need to connect two patches whose relative position can be defined only by a combination of a rotation + a translation.

Cyclic boundaries are perfect to do that, but the built-in solution allows only pure rotation or pure translation.

Does anybody have any idea how to implement rotation+translation cyclic boundaries ? Or is there some alternative built-in solution ?

Best regards,
