A topoSetCellSource
to select cells belonging to a topologically connected region (that contains given points). If started inside a given subCellSet
keeps to it; if started outside stays outside.
Operand | Type | Location |
---|---|---|
input | region | $FOAM_CASE/constant/{<region>, polyMesh} |
output | cellSet | $FOAM_CASE/constant/polyMesh/sets/<set> |
Example of the regionToCell
topoSet by using actions
sub-dictionary in system/topoSetDict
file:
{ // Mandatory (inherited) entries name <name>; type cellSet; action <action>; // Mandatory entries source regionToCell; insidePoints ( (<p1x> <p1y> <p1z>) (<p2x> <p2y> <p2z>) ... ); // Optional entries set <cellSetName>; nErode <label>; }
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: regionToCell | word | yes | - |
insidePoints | Coordinate(s) that is inside connected region | vectorList | yes | - |
set | Name of cellSet restricting search | word | no | none |
nErode | Number of cell layers to erode mesh to detect holes in the mesh - set to 0 if not used | label | 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
