Class
Foam::PLIC
Description
Piecewise-Linear Interface Calculation (PLIC) 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.
Example:
\verbatim
divSchemes
{
.
.
div(phi,alpha) Gauss PLIC interfaceCompression vanLeer 1;
.
.
}
\endverbatim
