A24. 2d propagation, showing Garden Sprinkler effect

The purpose of this test is to demonstrate the effect of directional resolution. A coarse resolution will lead to disintegration of the wave field.

2 cases are considered:

A24a
the default 2nd order upwind scheme with Δθ=10°
A24b
same with Δθ=2°

In both cases the geographical plots are in PostScript format.
