// This application/dictionary controls:
|
|
// - optional: create new patches from boundary faces (either given as
|
|
// a set of patches or as a faceSet)
|
|
// - always: order faces on coupled patches such that they are opposite. This
|
|
// is done for all coupled faces, not just for any patches created.
|
|
// - optional: synchronise points on coupled patches.
|
|
|
|
// 1. Create cyclic:
|
|
// - 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.
|
|
|
|
// 2. Correct incorrect cyclic:
|
|
// 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.
|
|
// - loosen match tolerance to get case to load
|
|
// - regenerate cyclic as above
|
|
|
|
// Tolerance used in matching faces. Absolute tolerance is span of
|
|
// face times this factor. To load incorrectly matches meshes set this
|
|
// to a higher value.
