Hello Everyone,

I'm trying to use a displacement motion in OpenFOAM for a certain boundary using the interpolation approach cause the displacementLaplacian at certain speeds fails and makes the boundaries go into each other at certain time steps and needs to go with very low time steps. So, I'm trying to use the displacementInterpolationFvMotionSolver; however, I don't have an example demonstrating the format of the interpolation tables that this class is searching for. Does anyone have any ideas on how to solve it or make the displacementLaplacian solver more robust?

Thanks a lot in advance!
