trying to couple a rotation movement with preCICE in OpenFOAM, I am facing the following problem:
Rotating a body using a Rotation Matrix (and displacing the body respectively with preCICE), the body starts deforming at the boundary of the patch, shaping the boundary “wave-like” (from this to that state).
Executing the same movement just with OpenFOAM (using
angularOscillatingDisplacement in the
pointDisplacement file), the body rotates normally without deformation.
A video of the motion can be found here.
To reproduce the issue, I have uploaded the case to Github:
