Hi Preeti,
There is no "BOTTOM" variable in your geometry file and Telemac tells you at the beginning of the computation:
FONSTR (BIEF): NO BATHYMETRY IN THE GEOMETRY FILE
AND NO BATHYMETRY FILE. THE BOTTOM
LEVEL IS FIXED TO ZERO BUT STILL
CAN BE MODIFIED IN CORFON.
Rename your "outermesh2_15_03" variable in the geometry file by "BOTTOM", and it should be better. Check also the values of the bathymetry on your boundary nodes with prescribed tide, there are strange values of about 0m while there are -3m next to.
Have a look at the numerous examples also.
And maybe, your boundary with prescribed tide is located to close to your area of interest. You should place it farer, in open sea.
Regards,
Laurent
