Detailed Description

Velocity-weighted Piecewise-Linear Interface Calculation (PLICU) 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 single 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 cut. For cases where the single-cut does not accurately represent the cell volume fraction the specified default scheme is used, e.g. interfaceCompression.

Additionally the face point velocity values are used to calculate the face flux which is likely to be more accurate in the presence of high shear.

Example:

    .
    .
    div(phi,alpha)     Gauss PLICU interfaceCompression vanLeer 1;
    .
    .
}
