Description
|
||||||
|
Calculate the dual of a polyMesh. Adheres to all the feature&patch edges.
|
||||||
|
|
||||||
|
Feature angle:
|
||||||
|
convex features : point becomes single boundary cell with multiple
|
||||||
|
boundary faces.
|
||||||
|
concave features: point becomes multiple boundary cells.
|
||||||
|
|
||||||
|
-splitAllFaces:
|
||||||
|
Normally only constructs a single face between two cells. This single face
|
||||||
|
might be too distorted. splitAllFaces will create a single face for every
|
||||||
|
original cell the face passes through. The mesh will thus have
|
||||||
|
multiple faces inbetween two cells! (so is not strictly upper-triangular
|
||||||
|
anymore - checkMesh will complain)
|
||||||
|
-doNotPreserveFaceZones:
|
||||||
|
By default all faceZones are preserved by marking all faces, edges and
|
||||||
|
points on them as features. The -doNotPreserveFaceZones disables this
|
||||||
|
behaviour.

meshDualiser
|
||||||
|
|
||||||
|
Description
|
||||||
|
Creates dual of polyMesh. Every point becomes a cell (or multiple cells
|
||||||
|
for feature points), a walk around every edge creates faces between them.
|
||||||
|
|
||||||
|
Put all points you want in the final mesh into featurePoints; all edge(mid)s
|
||||||
|
you want in the final mesh into featureEdges; all face(centre)s in
|
||||||
|
faceFaces.
|
||||||
|
|
||||||
|
Usually to preserve boundaries:
|
||||||
|
- all boundary faces are featureFaces
|
||||||
|
- all edges and points inbetween different patches are
|
||||||
|
featureEdges/points.
|
||||||
|
|
||||||
|
In same way you can also preserve internal faces (e.g. faceZones)
