open TELEMAC-MASCARET The mathematically superior suite of solvers

Hello ,

I have a problem in wave propgation . My input data are : Hs=4.7 ,T=9s ,Main Direction =121 North

Concerning the boundary conditions :

The south part are liquid imposed value , The North , West ,Est are solid boundaries .

For the steering file (Attached file PJ2)(I took minimum frequency =0.05) , the wave is not propagated .Even when i reduced the dissipation coeffecient .The results i have are in (attached PJ3)

I tried several configurations , the only one that gives a propagation of wave is with minimum frequency of the spectrum =0.5...But not logical my intial frequency is 0.11...and i just reached Value of H=0.2m (Attached PJ4)

I tried to run it for more time, changing the main direction (putting first 121 and then 301 following the tomawac conventions ), changing the time step , the numbers of direction and frequency ...I'm stuck for few days now and really don't know what to change.

Thank in advance for ur help!

Here is the mesh used .

Hello could you post the rest of the files needed for the simulation for a closer look? (Geometry file, boundary conditions file)

Andreas

Hello ,

Thank u for ur answer.
Find attached the files :





Mehdi !

Sorry i could not insert the bundaries file as an attached file...Here is the data :

Hello

Since you called your bathymetry New Mesh and not bottom or fond Tomawac didn't recognize it as a bathymetry then the bottom was set to 0 and then you tried to propagate wave height of 4.7m in 0.8m of water depth.
Call your BOTTOM 'BOTTOM' instead of 'new mesh' and it will propagate

Best regards
