open TELEMAC-MASCARET The mathematically superior suite of solvers

Hello everyone
My object is an island, so I want to know how to give opened boundary conditions on the edge of the island. BlueKenue can generate the closed boundary conditions and different boundary segments, but I need to generate opened boundary in all boundary points. I don't know how to do with Bluekenue.
Does anyone can help me ?
Best regards

Hi

Not sure to fully undertand what you want to do...
In BK, it's sometimes impossible to selected all nodes for a boundary as it automatically consider the small part between 2 nodes.
A trick will be to define 2 boundaries with a half of the boundary in each, separate by few solid nodes, generate the CLI file and manually change it to ensure to have only 1 liquid boundary

Hope this helps

Hi C.Coulet

Thank you for you reply.
My research is about rainfall and runoff in an island and I hope the rainwater can free flow out of the boundary. I want to give open boundary conditions with free depth and free velocity in all boundary points, but I can't find "open boundary with free H and V" in BlueKenue manual, I just need the open boundary.
And I have no idea about how to manually change the CLI file.

Best regards

Hi
You could try custom with Code 4 4 4
