Hey, I got an error notification when I tried to tun Telemac. And It's because one of the node was assigned with 2 kinds of boundary conditions. Here's the screenshot of the error message:

Now I have selected the wrong node, but can not find the tool to check and edit the boundary condition. could you please tell me how to do it? Or which chapter of Totorial I can refer to?

Thank you so much!

Hi
Look carefully at the message! The message about boundaries indicate a wrong mesh!
Then you cannot solve this problem by modifying the boundary condition.
You should work on your mesh

Hey, thank you so much for the reply.

I'm new to BlueKenue and TELEMAC. I am thinking maybe it's just Point 10718 is wrong ? Do I need to create an entire new mesh ? Or just correct this point? If so, which tool should I use?

Thank you !

Hard to say as the error stop the execution and then maybe another point is wrong at another place...
Give us the mesh will help us to have a more precise idea of the problem...

Another hint...
If you modified the mesh in any way you have to rebuild the boundary conditions...

According to what I saw rapidly, this is not the only point on boundary with this problem...
You should work on your mesh and regenerate it with a finer density or an adapted outline...

Thank you. Does the finer density mean the lower default edge length value when running T3 Mesh Generation? And the outline file is provided by my advisor, I will try to lower the default edge length value and recreate mesh if I understand your instructions correctly:) Thank you !!!

It depends how you define the mesh density!
Even the outline is provided by you advisor, the details should be coherent with the required mesh size...

Hi,

Here are 3 of many problem areas in your mesh.

It's not going to be fixed by lowering the default edge length.
I suggest you resample the outline to half of the current internode
spacing.
Alternatively trim those small areas out.
Their absence likely won't influence the results of your simulation.

Cheers... Martin
