| Class | |
| Foam::interfaceCompressionFvPatchScalarField | |
| Description | |
| Applies interface-compression to the phase-fraction distribution at the | |
| patch by setting the phase-fraction to 0 if it is below 0.5, otherwise | |
| to 1. | |
| This approach is useful to avoid unphysical "bleed" of the lighter phase | |
| along the surface in regions of high shear adjacent to the surface which | |
| is at a shallow angle to the interface. | |
