A topoSetCellSource to select cells based on a target volume of cells. Adapts a plane until it has enough.


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


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

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

    // Mandatory entries
    source      targetVolumeToCell;
    volume      10;
    normal      (1 0 0);

    // Optional entries
    set         <cellSetName>;

where the entries mean:

Property Description Type Required Default
name Name of cellSet word yes -
type Type name: cellSet word yes -
action Action applied on cells - see below word yes -
source Source name: targetVolumeToCell word yes -
volume The target volume [m3] scalar yes -
normal The plane normal vector yes -
set Restrict to named cellSet word no ""

Options for the action entry:

new      | Create a new cellSet from selected cells
add      | Add selected cells into this cellSet
subtract | Remove selected cells from this cellSet
