Subject: [PATCH] tutorials/lagrangian/reactingParcelFoam/splashPanel: Resolved
 divergence

The side surfaces in this tutorial have been made symmetry planes to
match the corresponding boundaries in the film region, and the top has
had its pressure condition changed to totalPressure. The case now runs
successfully to completion.

Previously the pressure-velocity boundary condition combination on the
non-film patches was incorrect in that in regions of outflow a pressure
value was not being specified. This resulted in divergence.

-// This application/dictionary controls:

-//   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
-// - 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
-
