A topoSetPointSource to select all points which are inside a given bounding cylinder or cylinder annulus.


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


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

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

    // Mandatory entries
    source      cylinderToPoint;
    p1          (<p1X> <p1Y> <p1Z>);
    p2          (<p2X> <p2Y> <p2Z>);
    radius      <radius1>;

    // Optional entries
    innerRadius <radius2>;

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: cylinderToPoint word yes -
p1 Coordinate of one of the endpoints vector yes -
p2 Coordinate of the other endpoint vector yes -
radius Cylinder outer radius scalar yes -
innerRadius Cylinder inner radius 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
