Hi,

I have successfully ran the culvert example provided in TELEMAC-3D validation manual using TELEMAC-3D (chapter 15, schematic culvert test case). I then tried to run the same example, using TELEMAC-2D.

I edited the cas steering file to make sure that the keywords are compatible with TELEMAC-2D, and remove a few of them which do not have comparable keywords in TELEMAC-2D (e.g. number of horizontal levels). However, I obtained error "EQUNOR (BIEF) : EXCEEDING MAXIMUM ITERATIONS".

Attached is the edited steering file. May I seek your advice on what went wrong and how can I fix this issue? My apology if this is too basic

Hope this helps, Chi-Tuan
