A36. Diffraction test with semi-infInite breakwater
In this test results for Swan with diffraction are compared with
the analytic solution by Sommerfeld for monochromatic
and uni-directional incident waves.
The results are compared for three semi-circles all having the breakwater
tip as their centre. The radii of the semi-circles are 2L, 3L and 5L,
where L is the wave length (39 m in this case).
4 cases are considered:
Run A36b is not Included in the graphs because the diffraction approximation is unstable without smoothing (this is standard in the present distributed version of Swan).
