stitchMesh
|
|
|
|
Description
|
|
Utility to stitch or conform pairs of patches,
|
|
converting the patch faces either into internal faces
|
|
or conformal faces or another patch.
|
|
|
|
Usage
|
|
\b stitchMesh (\<list of patch pairs\>)
|
|
|
|
E.g. to stitch patches \c top1 to \c top2 and \c bottom1 to \c bottom2
|
|
stitchMesh "((top1 top2) (bottom1 bottom2))"
|
|
|
|
Options:
|
|
- \par -overwrite \n
|
|
Replace the old mesh with the new one, rather than writing the new one
|
|
into a separate time directory
|
|
|
|
- \par -region \<name\>
|
|
Specify an alternative mesh region.
|
|
|
|
- \par -fields
|
|
Update vol and point fields
|
|
|
|
- \par -tol
|
|
Merge tolerance relative to local edge length (default 1e-4)
|
