DISPLAY
This case concerns potential flow around a 2D aerofoil.
A single domain grid is used, and it is joined to itself
by means of a non-natural link. The link is non-natural
in the sense that it is SOUTH-SOUTH rather than SOUTH-
NORTH. These links are supported only for the
solution of scalar variables. The link is set manually
using PATCH commands rather than MBLINK PIL-command.
Q1-file contains Photon Use information.
