Description

A topoSetCellSource to select all cells whose cell centre inside a given bounding cylinder annulus.

Operands

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

Description

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

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

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

    // Optional entries
    innerRadius <radius2>;
}

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: cylinderAnnulusToCell	word	yes	-
p1	Coordinate of one of the endpoints	vector	yes	-
p2	Coordinate of the other endpoint	vector	yes	-
outerRadius	Cylinder outer radius	scalar	yes	-
innerRadius	Cylinder inner radius	scalar	no	0

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
