Hi everybody

I hope someone can help me. I am a openfoam beginner and with little knowledge of c++.

I modified the solver pimpleDyMFoam to calculate the boundary motion of my mesh according to the flow results (a solution dependent boundary motion).

My problem is that i have calculated the magnetude of the displacement velocity at the cell centers (volScalarField) and the velocityComponentLaplacian requires me the displacement velocity at the cell nodes (is it a pointScalarField or something else???).

I could see that there was some previous discussions in the forum about this (e.g. fvMotionSolver). Is the fvMotionSolver the only solution or is there some other simpler interpolation procedure for this?

Thanks

Luca
