open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi,

I am trying to perform Fourier analysis on my tidal simulation.

I use the following keywords in my .cas file

FOURIER ANALYSIS PERIODS = 8640 (in time-steps)
TIME RANGE FOR FOURIER ANALYSIS = 0;2851200 (in seconds)

However, the results return incorrect values especially for amplitude which are a order of magnitude lower than expected.
Am I taking the correct approach to using this TELEMAC-2D feature?

Hello,

I would rather give FOURIER ANALYSIS PERIODS with periods of waves in seconds. You can start e.g. with 44714.
You can have a look at the telemac2d/m2wave/t2d_m2wave.cas example.

Hope this helps,

Chi-Tuan
