27 Description
28  Provides functions smooth spread and sweep which use the FaceCellWave
29  algorithm to smooth and redistribute the first field argument.
30 
31  smooth: smooths the field by ensuring the values in neighbouring cells are
32  at least coeff* the cell value.
33 
34  spread: redistributes the field by spreading the maximum value within the
35  region defined by the value (being between alphaMax and alphaMin)
36  and gradient of alpha (where the difference between the values in
37  neighbouring cells is larger than alphaDiff).
38 
39  sweep: redistributes the field by sweeping the maximum value where the
40  gradient of alpha is large (where the difference between the values
41  in neighbouring cells is larger than alphaDiff) away from that
42  starting point of the sweep.
