Motion Solver imposed on face centers?
 

Hello,
I am trying to understand if in OF exist a motion solver where you can specify the motion just on the face center of the boundary and not on the points.

From what I know, LaplaceDisplacement requires a pointDisplacement (point), LaplaceVelocity a cellMotion(face) AND pointMotion (point), the FEM solvers(i.e. laplaceFaceDecomposition) requires motionU(face and points of the tet mesh).

Is there any solver that requires the motion to be specified only on the faceCentres? And if yes, does it work in parallel?I presume it may not be easy to ensure that points shared by more than partition moves exactly the same if I impose the motion just on the the face centers...


Thank you very much,
Matteo
