Description

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
