Class
Foam::sampledSurfaces::patch
Description
A sampledSurface on patches. Non-triangulated by default.
Example:
\verbatim
{
type patch;
patches (walls);
triangulate no;
interpolate yes;
}
\endverbatim
Usage
\table
Property | Description | Required | Default value
patches | the names of patches on which to sample | yes |
triangulate | triangulate the output | no | no
interpolate | interpolate values to the surface points | no | no
\endtable
