G05. Convergence with different initial conditions

The purpose of this series of tests is to verify whether the converged result is independent of Initial conditions and numerics (such as resolution).
It is seen that the spectra converge to one and the same limiting spectrum. Due to relatively crude iteration termination criteria the iteration stops before very close agreement is reached. The agreement is worst if the Initial wave field is almost perpendicular to the wind direction. The quantity where the differences ar the largest is the average direction of the limit spectrum.
The results are inspected by means of plots G05b.spl and G05c.spl.

2 series of runs are made:

G05a1 .. G05a7
Runs with option NOUPDATE to verify whether initial conditions are correctly implemented
G05b1 .. G05b7
series of runs with different average directions of the initial spectrum; the directions are 0°, 30°, 60°, 90°, 120°, 150°, 180°.
