Regarding cellDisplacement and pointDisplacement
 

Hi guys,

I've been having some strange results with dynamic mesh, with the volumetric values of cellDisplacement returning the correct value in a modified pimpleDymFoam, but the point values for cellDisplacement and pointDisplacement both showed no movement at all. Any one know what might have caused this? I'm using dynamicMotionSolverFvMesh and libfvMotionSolvers.so with displacementLaplacian & inverseDistance.
I'm wondering if this has something to do with my dynamicDict setup or if it is a problem with the modification I did to the code.

Thanks

John

EDIT: It turns out that I messed up the boundary condition setting and enforced "fixedValue" pointDisplacement field instead of symmetryPlane, which forces the side mesh to remain stationary.
