ASCII atmospheric data_pressure

Hello [name removed],

I am a beginner user of Telemac2D. For a coastal flooding simulation, I wanted to add the option for atmospheric pressure variation (spatially constant) using an ASCII file. I consulted the user guide (the steering file and ASCII file are attached). The results show no difference between the water level with the tide alone and the level with the atmospheric pressure included. I would appreciate your help.

Best regards.

Hi

I didn’t checked but it seems to me that the atmospheric pressure is implemented only in terms of spatial gradient then just changing the value everywhere doesn’t change the result…

Hope this helps

Thanks to your response,

How do I ensure that the change in atmospheric pressure values ​​takes effect on the water level?

4

if possible, your could try to use a spatially variable pressure…

As I use it for cyclonic simulation, with atmospheric file, I’m sure it works…

Hi,

the atmospheric file you are using is for cyclonic simulation is Binary file containing wind and pressure right?

Thanks,

yes

Hello,

I have 2 kind of error messages when I try to use API (even with my own profile) or local downloaded grib file from copernicus ERA5 when I use converter ecmwf2srf
