**Original source file** fvcSmooth.H

InNamespace Foam::fvc

smooth: smooths the field by ensuring the values in neighbouring cells are at least coeff* the cell value.

spread: redistributes the field by spreading the maximum value within the region defined by the value (being between alphaMax and alphaMin) and gradient of alpha (where the difference between the values in neighbouring cells is larger than alphaDiff).

sweep: redistributes the field by sweeping the maximum value where the gradient of alpha is large (where the difference between the values in neighbouring cells is larger than alphaDiff) away from that starting point of the sweep.
