- ditched PrimitivePatchExtra in favour of a PatchTools class that is currently just a collection of static functions. They could equally well live within PrimitivePatch itself, but isolated also has its advantages. - MeshedSurface, UnsortedMeshedSurface now have 'regions' instead of 'patches' since they are more like a faceZone for meshed surfaces than patches. This might avoid confusion at a later stage.

Foam::cyclicPolyPatch
|
|
|
|
Description
|
|
Cyclic plane patch.
|
|
|
|
Note: morph patch face ordering uses geometric matching so with the
|
|
following restrictions:
|
|
-halves should be flat planes.
|
|
-no rotation in patch plane
|
|
|
|
Uses a featureCos to find the two halves (or should be fully
|
|
disconnected). Uses coupledPolyPatch::calcFaceTol to calculate
|
|
tolerance per face which might need tweaking.
|
|
|
|
Switch on 'cyclicPolyPatch' debug flag to write .obj files to show
|
|
the matching.
