Description

A topoSetFaceSource to select faces based on usage in another faceSet.

Operands

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

Description

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

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

    // Mandatory entries
    source      faceToFace;

    // Conditional mandatory entries
    // Select either of the below

    // Option-1
    sets
    (
        <faceSetName0>
        <faceSetName1>
        ...
    );

    // Option-2 
    set     <faceSetName>;
}

where the entries mean:

Property	Description	Type	Required	Default
name	Name of faceSet	word	yes	-
type	Type name: faceSet	word	yes	-
action	Action applied on faces - see below	word	yes	-
source	Source name: faceToFace	word	yes	-

Options for the action entry:

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

Options for the conditional mandatory entries:

Entry    | Description                | Type     | Required    | Default
sets     | Names of input faceSets    | wordList | conditional | -
set      | Name of input faceSet      | word     | conditional | -

Notes on entries

The order of precedence among the conditional mandatory entries from the highest to the lowest is sets, and set.
