Class
Foam::sampledSurfaces::distanceSurface
Description
A sampledSurface defined by a distance to a surface.
Example:
\verbatim
{
type distanceSurface;
surfaceType searchableBox;
min (-1 -1 -1);
max (1 1 1);
distance 0.1;
signed yes;
interpolate yes;
}
\endverbatim
Usage
\table
Property | Description | Required | Default value
surfaceType | The type of surface to sample from | yes |
distance | The distance from which to sample the surface | yes |
signed | Sample only on one side of the surface? | yes |
interpolate | Interpolate values to the surface points? | no | no
cellZone | Zone containing cells to include | no | all
\endtable
