| Foam::surfaceToCell | |
| Description | |
| A topoSetSource to select cells based on relation to surface. | |
| Selects: | |
| - all cells inside/outside/cut by surface | |
| - all cells inside/outside surface ('useSurfaceOrientation', requires closed | |
| surface) | |
| - cells with centre nearer than XXX to surface | |
| - cells with centre nearer than XXX to surface \b and with normal | |
| at nearest point to centre and cell-corners differing by | |
| more than YYY (i.e., point of high curvature) | |
