27 Description
28  Multicut Piecewise-Linear Interface Calculation (MPLIC) corrected scheme is
29  a surface interpolation scheme for flux calculation in advection of a
30  bounded variable, e.g. phase fraction and for interface capturing in the
31  volume of fluid (VoF) method.
32 
33  The interface is represented by multiple cuts which split each cell to match
34  the volume fraction of the phase in the cell. The cut planes are oriented
35  according to the point field of the local phase fraction. The phase
36  fraction at each cell face - the interpolated value - is then calculated
37  from the face area on either side of the cuts.
38 
39  Three progressively more complex algorithms are used to ensure the cell
40  volume fraction is accurately reproduced:
41  -# single cut: cuts all the cell faces regardless the order
42  -# multi cut: topological face-edge-face walk which can split cell into
43  multiple sub-volumes
44  -# tetrahedron cut: decomposes cell into tetrahedrons which are cut
45 
46  Example:
47  \verbatim
48  divSchemes
49  {
50  .
51  .
52  div(phi,alpha) Gauss MPLIC;
53  .
54  .
55  }
