Operands

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

Description

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

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

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

    // Optional entries
    innerRadius 0;
}

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: sphereToCell	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 cellSet from selected cells
add      | Add selected cells into this cellSet
subtract | Remove selected cells from this cellSet
