Airflow over a flat plate with a blunt fin rising from the plate.
Free stream flow direction is parallel to the plate and to the flat
part of the fin, entirely in the x component direction. The flow is
assumed to be symmetrical about a plane through the center of the fin,
so only one half of the "real" geometry is present and used in the
computation.

Visualization
This is the teapot of CFD visualization.
Interesting features of this flow are the branching structure of the
shock in front of the leading edge of the fin (called a "lambda shock"
due to its shape) and the two counter-rotating vortices, separated by
a branch of the shock. One vortex is rooted between the shock and the
edge of the fin; the other vortex is rooted between the shock and the
plate, just upstream of the fin.
The plate is found at K = 1, and the fin at j = 1.
These visualize the vortex cores and density on the fin and plate:
This is a smaller version of the same visualization, but it
is somewhat inaccurate because of data aliasing.
