A topoSetSource to select faces based on usage in a faceSet, where the normal vector is used to orient the faces.


Operand Type Location
input faceSet $FOAM_CASE/constant/polyMesh/sets/<set>
output faceZone $FOAM_CASE/constant/polyMesh/faceZones


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

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

    // Mandatory entries
    source      setAndNormalToFaceZone;
    faceSet     <faceSetName>;
    normal      (1 0 0);

where the entries mean:

Property Description Type Required Default
name Name of faceZone word yes -
type Type name: faceZone word yes -
action Action applied on faces - see below word yes -
source Source name: setAndNormalToFaceZone word yes -
faceSet Name of input faceSet word yes -
normal The normal vector for orientation vector yes -

Options for the action entry:

new      | Create a new faceZone from selected faces of a faceZone
add      | Add selected faces of a faceZone into this faceZone
subtract | Remove selected faces of a faceZone from this faceZone
