open TELEMAC-MASCARET The mathematically superior suite of solvers

Hello
I encountered a problem while simulating city flooding. After I prepared all the files, the following error occurred while running the simulation.

I tried to recreate the cli and slf files many times, but it didn't work. I uploaded My bluekenue workspace and cas files, I hope someone can help me check the errors in the files and teach me how to modify them.
Thank you very much！

Hi Barry,

There are many problem areas in your mesh.
You should be using smaller elements to resolve
the roads.

The "point on multiple boundaries" message is due to
features like those circled in red in the attached image.

Hope this helps... Martin

Thank you！it did work after I removed some wrong mesh
