A topoSetPointSource to select points which are inside a given bounding sphere.


Operand Type Location
output pointSet $FOAM_CASE/constant/polyMesh/sets/<set>


Example of the sphereToPoint topoSet by using actions sub-dictionary in system/topoSetDict file:

    // Mandatory (inherited) entries
    name        <name>;
    type        pointSet;
    action      <action>;

    // Mandatory entries
    source      sphereToPoint;
    origin      (0 0 0);
    radius      0.5;

    // Optional entries
    innerRadius 0;

where the entries mean:

Property Description Type Required Default
name Name of pointSet word yes -
type Type name: pointSet word yes -
action Action applied on points - see below word yes -
source Source name: sphereToPoint word yes -
origin The origin (centre) of the sphere vector yes -
radius The (outer) radius of sphere scalar yes -
innerRadius The inner radius of sphere scalar no 0

Options for the action entry:

new      | Create a new pointSet from selected points
add      | Add selected points into this pointSet
subtract | Remove selected points from this pointSet
