[swanmodel-users] Unstructured grid_Boundary conditions definition

[Ahmad K. (Student) <ah...@ma...>]

Dear All,


I am using an unstructured grid generated by triangle, and I am facing a problem defining the boundary conditions. The solution is good if I use the SIDE command, but when I use SEGMENT the hole grid is messed up. I am defining boundary on one side using SEGMENT,  and it seems like the boundary of those segments is leaking through all the other sides, and into the grid as well.

That did not happen for structured grid.

Any Suggestions?


This is the SWAN file I am using:
