Description
'Stitches' a mesh.
Takes a mesh and two patches and merges the faces on the two patches
(if geometrically possible) so the faces become internal.
Can do
- 'perfect' match: faces and points on patches align exactly. Order might
be different though.
- 'integral' match: where the surfaces on both patches exactly
match but the individual faces not
- 'partial' match: where the non-overlapping part of the surface remains
in the respective patch.
Note : Is just a front-end to perfectInterface/slidingInterface.
Comparable to running a meshModifier of the form
(if masterPatch is called "M" and slavePatch "S"):
couple
{
type slidingInterface;
masterFaceZoneName MSMasterZone
slaveFaceZoneName MSSlaveZone
cutPointZoneName MSCutPointZone
cutFaceZoneName MSCutFaceZone
masterPatchName M;
slavePatchName S;
typeOfMatch partial or integral
}
