Hi
I find in pimpleDynamicFoam and icoDyMFoam, there are some operation about fvc::makeRelative(phi, U) and fvc::makeAbsolute(phi, U), I know what it means, but do not know why to do this. Who can told me the reason or provide me some papers about this? Thanks.

Hey,
I think these operations are used if your meshing is moving(not refine).
But I am not quite sure.

I think so. But what I want to know is the purpose of doing this.
