Using mapFields on a moving grid

Reptider · June 24, 2021, 03:59

Hello!
I have a situation where the grid changes at every time step so I need to map all fields to modified grid. There is only one external patch - movingWall.
Under certain conditions, this grid only changes in a few places that I can't determine explicitly.
mapFields requires patchMap and cuttingPatches. Which option should I use in my case?
Thank you!
Can I use only cuttingPatches? Will there be some problems on the new patch in places where deformation on the grid does not occur?

Hi!

Why do you need to map? If the motion is made by a dynamicMesh lib, it'll map for you without any extra commands...
