Hi all,

I'm using mesh motion with the displacementLaplacian solver and a modified interDymFoam solver. During runtime, the points on the bottom boundary patch, i.e. in the boundaryField, are modified and used as a boundary condition for the whole mesh motion.

As my mesh somewhen gets distorted (I guess due to the fact that only the patch motion is given as a boundary condition), I'd like to move the cells (centroids) connected to the bottom patch as well, before the mesh motion solver is starting its job.

Is this possible, and if so, how? My problem is that these cells are of course in the internalField, whereas the motion of the other cells of the internalField is not known at this stage.
