open TELEMAC-MASCARET The mathematically superior suite of solvers

Dear friends
I have been simulating velocity and water depth of a meandering river with telemac2d these days.A difficulty in attachments always troubled me.I have tried many times with the same stetting except the caculatation mesh(but with the same Edge growth ratio 1.2 and Default edge length 2).However,sometimes I can get success, sometimes I get failed as attachments.Could you tell me what mistake I have make and what should I do.

Hi
What you should do is very simple:

• read the user manual
• search in the forum as this problem has been treated many many times

This is not linked to your mesh but to your settings (initial condition).

Regards
