The FOAM file format has not changed from version 2.0 in many years and so there is no longer a need for the 'version' entry in the FoamFile header to be required and to reduce unnecessary clutter it is now optional, defaulting to the current file format 2.0.

// 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.
|
|
// - always: remove zero-sized (non-coupled) patches (that were not added)
|
|
|
|
// 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
|
|
// - always create both halves in one invocation with correct 'neighbourPatch'
|
|
// setting.
|
|
// - optionally 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."
|
|
// - in polyMesh/boundary file:
|
|
// - loosen matchTolerance of all cyclics to get case to load
|
|
// - or change patch type from 'cyclic' to 'patch'
|
|
// and regenerate cyclic as above
|
|
|
|
// Do a synchronisation of coupled points after creation of any patches.
|
|
// Note: this does not work with points that are on multiple coupled patches
|
|
// with transformations (i.e. cyclics).
