| Foam::sampledSurfaces::triSurface | |
| Description | |
| A sampledSurface from a triSurface. It samples on the points/triangles | |
| of the triSurface. It either samples cells or (non-coupled) boundary faces. | |
| There are 6 possible modes: | |
| - source=cells, interpolate=false: | |
| Finds per triangle centre the nearest cell centre and uses its value. | |
| - source=cells, interpolate=true | |
| Finds per triangle centre the nearest cell centre. Per surface point | |
| checks if this nearest cell is the one containing point; otherwise | |
| projects the point onto the nearest point on the boundary of the cell | |
| (to make sure interpolateCellPoint gets a valid location) | |
| - source=insideCells, interpolate=false: | |
| Finds per triangle centre the cell containing it and uses its value. | |
| Trims triangles outside mesh. | |
| - source=insideCells, interpolate=true | |
| Per surface point interpolate cell containing it. | |
| - source=boundaryFaces, interpolate=false: | |
| Finds per triangle centre the nearest point on the boundary (uncoupled | |
| faces only) and uses the value (or 0 if the nearest is on an empty | |
| boundary). | |
| - source=boundaryFaces, interpolate=true: | |
| Finds per triangle centre the nearest point on the boundary (uncoupled | |
| faces only). Per surface point projects the point onto this boundary | |
| face (to make sure interpolateCellPoint gets a valid location) | |
| Since it finds a nearest per triangle each triangle is guaranteed to be on | |
| one processor only. So after stitching (by sampledSurfaces) the original | |
| surface should be complete. | |
| Example: | |
| \verbatim | |
| { | |
| type triSurface; | |
| surface "surface.stl"; | |
| source cells; | |
| interpolate yes; | |
| } | |
| \endverbatim | |
