open TELEMAC-MASCARET The mathematically superior suite of solvers

Hello to everyone,

I am using MEDSEA_ANALYSIS_FORECAST_PHY_006_013
outputs to force telemac3d . It seems that my current profiles are well putted on the boundary limits.
I failed to use Thompson method as an option for the liquid boundaries. The classical option gave the attached result which looks erroneous on the west side of the domain .

I also attached the steering file which may help


I will highly appreciate any assistance. Thank you.

Hello,

What exactly fails when you use Thompson option?
It also depends on your settings and what quantities you're prescribing on your liquid boundaries: 3D currents, 2D currents, surface elevations, T/S?
If the west/south boundaries of your domain are ok, there is no reason for the east boundary not to be... that seems not too far from your forcing field by the way (only on boundary nodes, not inside the domain).

Hello Laurent,

the only boundary inputs are 3D currents.

Here are attached the results of the Thompson option:


Hope this can help.

Hi,

Do you let the free surface free or imposed to 0?
The results you're showing seem to be the last outputs of the run, how the first iterations look like? for velocity and surface elevation?
It's possible that Thompson option is not the best setting in your case.

Regards,
Laurent

Its looks better with free surface.




I will try to put the free surface as boundary forcing.
