I would like to use the "mapped boundary condition" as the recycling method to specify inlet boundary condition for LES simulation, so that the field U and k on a certain plane downstream of the inlet is mapped back to the inlet for the next time step.
I read through the thread
mapped boundary condition
and the code guide
https://www.openfoam.com/documentati...e.html#details

Does anyone know what do the following choices mean:

- nearestCell : sample cell containing point
- nearestOnlyCell : nearest sample cell (even if not containing point)
- nearestPatchFace : nearest face on selected patch
- nearestPatchFaceAMI : nearest face on selected patch
A.patches need not conform
B. uses AMI interpolation
- nearestFace : nearest boundary face on any patch
- nearestPatchPoint : nearest patch point (for coupled points this might be any of the points so you have to guarantee the point data is synchronised beforehand)

Thanks
