fix the amplitude of the 3D TS waves to match the Schlatter 2005 case #1342

Closed pschlatt1 closed 2 days ago

also added a ipynb notebook to plot the TS waves.

This case could eventually be aded to the CI to verify the code accuracy once we have an established baseline from Simson.

The original setting follows p40 in Schlatter 2005. And how does it come to 5e-4?

pschlatt1 commented 3 days ago

The velocity magnitude (in centre-line velocity) in Schlatter 2005 is 0.1%, i.e. 0.001. SInce we have two oblique waves, they have individually 0.0005 as peak amplitude, which is 5e-4 for each wave.

Ah yes. I overlooked we have two waves (and maybe the 1e-4 in the previous code was a typo)
