Description

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

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

    // Mandatory entries
    source      shapeToCell;
    shape       <shapeTypeName>;
}

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: shapeToCell	word	yes	-
shape	Type of cell shape - 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 shape entry:

splitHex   | Split-hexahedra cells
