|
// - optional: create new patches from boundary faces (either given as

|
// a set of patches or as a faceSet)
|
||

// is done for all coupled faces, not just for any patches created.

|
||
|
|
// - specify where the faces should come from
|
||
|
|
// - specify the type of cyclic. If a rotational specify the rotationAxis
|
||
|
|
// and centre to make matching easier
|
||
|
|
// - pointSync true to guarantee points to line up.

// This will usually fail upon loading:
|

// "face 0 area does not match neighbour 2 by 0.0100005%"

// " -- possible face ordering problem."

// - change patch type from 'cyclic' to 'patch' in the polyMesh/boundary file.
