Detailed Description

Multicut Piecewise-Linear Interface Calculation (MPLIC) corrected scheme is a surface interpolation scheme for flux calculation in advection of a bounded variable, e.g. phase fraction and for interface capturing in the volume of fluid (VoF) method.

The interface is represented by multiple cuts which split each cell to match the volume fraction of the phase in the cell. The cut planes are oriented according to the point field of the local phase fraction. The phase fraction at each cell face - the interpolated value - is then calculated from the face area on either side of the cuts.

Three progressively more complex algorithms are used to ensure the cell volume fraction is accurately reproduced:

single cut: cuts all the cell faces regardless the order
multi cut: topological face-edge-face walk which can split cell into multiple sub-volumes
tetrahedron cut: decomposes cell into tetrahedrons which are cut

Example:

divSchemes
{
    .
    .
    div(phi,alpha)      Gauss MPLIC;
    .
    .
}
