Provides functions smooth spread and sweep which use the FaceCellWave
algorithm to smooth and redistribute the first field argument.
smooth: smooths the field by ensuring the values in neighbouring
cells are at least coeff* the cell value.
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 and gradient of alpha.
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 away from that starting point of the
sweep.
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.
