Description

A topoSetCellSource to select cells with any point or any edge within a given pointSet(s).

Operands

Operand	Type	Location
input	pointSet(s)	$FOAM_CASE/constant/polyMesh/sets/<set>
output	cellSet	$FOAM_CASE/constant/polyMesh/sets/<set>

Description

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

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

    // Mandatory entries
    source      pointToCell;
    option      <option>;

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

    // Option-1
    sets
    (
        <pointSetName1>
        <pointSetName2>
        ...
    );

    // Option-2
    set   <pointSetName>;
}

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: pointToCell	word	yes	-
option	Selection type - see below	word	yes	-

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

Options for the option entry:

any     | Cells using any point in pointSet
edge    | Cells using an edge with both points in pointSet

Options for the conditional mandatory entries:

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

Notes on entries

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