open TELEMAC-MASCARET The mathematically superior suite of solvers

Hello,

I wish to couple my North Sea T3D model (including the French continental shelf) with TOMAWAC.
I've seen that the vortex force equations have been implemented in T3D, but unfortunately, the implementation doesn't seem to be compatible with the keyword SPHERICAL COORDINATES = YES, which is a problem for such a large domain since I'd need the Coriolis coefficient to be variable.

Therefore, for now, the standard implementation of the depth-uniform radiation stress will do the trick.

The issue is that when I run my T3D model coupled with TOMAWAC, I have no error message, T3D and TOMAWAC run with no issue, but in the end, the water levels are not changed at all in T3D compared with a non-coupled simulation.
I wonder if I did something wrong?

I attached the steering files, the mesh and the boundary condition files, if necessary, I can upload on another platform the tpxo and wind files.

Thank you for your help!

I just upgraded my TELEMAC version to the latest available on gitlab (I was working with v8p5 from almost a year ago), the problem seems to have been solved.

For my information, is it planned to make the coupling with TOMAWACT3D (VF formalism) compatible with spherical coordinates? How hard would it be to modify it?

Hello,
I encountered the same same problem as you. I'm trying to couple t3d with tomawac, but it printed out that 3D COUPLING WITH TOMAWAC NOT IMPLEMENTEDIN SPHERICAL COORDINATES. I don't konw how to slove this problem. My version is V8P4.
You mentioned that your problem has been sloved successfully by upgrading your TELEMAC version, could you tell me which version I should download ?
Thank you for your help!

Hi, if you upgrade to V8P5, you'll be able to do the coupling with the standard option (COUPLING WITH : 'TOMAWAC'), which is based on depth-uniform radiation stress gradients.

However if you want to use the more accurate vortex force formalism (COUPLING WITH 'TOMAWACT3D'), along with the use of spherical coordinates, I believe it's still not implemented, and even wonder if it will be one day.

Hello Hedi,

I think the following post can give good explanations of the issue:
