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.

Class
|
||||
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)
