A topoSetCellSource
to select cells based on relation to a surface given by an external file.
surfaceToCell
can select:
useSurfaceOrientation
, requires closed surface)Operand | Type | Location |
---|---|---|
input | triSurface | $FOAM_CASE/constant/triSurface/<file> |
output | cellSet | $FOAM_CASE/constant/polyMesh/sets/<set> |
Example of the surfaceToCell
topoSet by using actions
sub-dictionary in system/topoSetDict
file:
{ // Mandatory (inherited) entries name <name>; type cellSet; action <action>; // Mandatory entries source surfaceToCell; file <surfaceFileName>; outsidePoints ( (<p1x> <p1y> <p1z>) (<p2x> <p2y> <p2z>) ... ); includeCut false; includeInside false; includeOutside true; nearDistance 0.5; curvature 1.0; // Optional entries useSurfaceOrientation false; fileType stl; scale 2.0;
}
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: surfaceToCell | word | yes | - |
file | The surface "filename" | word | yes | - |
outsidePoints | List of points that define outside of the surface | vectorList | yes | - |
includeCut | Flag to include cut cells | bool | yes | - |
includeInside | Flag to include inside cells | bool | yes | - |
includeOutside | Flag to include outside cells | bool | yes | - |
useSurfaceOrientation | Flag to use inherently the orientation of the surface | bool | no | false |
nearDistance | Near distance to the surface | scalar | yes | - |
curvature | Surface curvature | scalar | yes | - |
fileType | The format of the surface file | word | no | "" |
scale | Surface scaling factor | scalar | no | -1 |
Options for the action
entry:
