open TELEMAC-MASCARET The mathematically superior suite of solvers

Hello teacher, I don't want to re-post questions on the same subject, so I reply to you again, thank ypu.

For the Gulf tide, I set up a new mesh at the same location in Spain. I also gave basic parameters based on the manual and example "tide", and it runs smoothly.

However, the result of the “free surface” is very BAD. It is obviously not on the normal level at the Geo-Bottom, and the water level is much higher. This is very unnormal water flow, I think.

But for H and UV with open boundaries, I did n’t assign any values. These values ​​are all from the TPXO database, right? so what should do check my model and improve it rightly.

I am very confused about this, I attach a BK post-pre photo that compare it with the example "tide". And my output file, and steering file. If you need to check more files of my simulations, please let me know.

thanks a lot!
All regards
