triangulation failed

Dear all,

I am beginner of MIKE 21. When I follow example described in "MIKE FD HD step by step", I can not triangluate domain well . The error occurs "Triangulation failed: Input data could not be triangulated", I do not undersatand the reason while tutorial does not mention about this issue.

Can you show me how to solve this issue?

Thanks a lot

Best regards,

Hi,

do you have crossing arcs in your Arcs - File ?
Another reason could be nests of nodes / vertices very close together.

Please try to clean your arcs and redistribute vertices.
