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 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.



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.
