open TELEMAC-MASCARET The mathematically superior suite of solvers

Hello Forum,

I am trying to run a simulation on storm surges caused by a winter storm along the British coast with TELEMAC 2D. I have already obtained adequate results by importing the pressure field and wind field with the keyword 'BINARY ATMOSPHERIC DATA FILE'. Now I would like to improve the results by coupling TELEMAC 2D with TOMAWAC and import the effects of wave driven currents. However, when coupling the 2 modules, although the simulation seemed to run correctly till the end, when I checked the result file, the values 'WIND ALONG' in the TOMAWAC result file appeared to be 'NaN', and apparently the wind effect was not counted during the simulation of TOMAWAC.I find it strange because 'partel' seemed to be running correctly and the wind data appeared to be correctly read and split by the process. I tried to run a standalone TOMAWAC Simulation with the same steering file, input files and settings and everything went fine, this problem only occurs when I tried to couple with TELEMAC 2D. Has anyone ever encountered a problem like this?

Just for information: I'm running tag v7p2r3 on Ubuntu 16.04.

Thanks for any help~

Hello

If I remember well, we observed some weired results with v7p2 and several fixes were intriduced in v7p3.
What you can do is just compare the last part of subroutine prosou.f (sources/telemac2d) between v7p2 and v7p3. Then you add this subroutine to your fortran file and update the lines dealing with wave driven currents (line 649 and more).
I'm not sure that there is other thing to change. Just try it and hopefully it will work. Otherwise you need to update to v7p3.

kind regards

Hello Riadh,

Thanks, I will try to fix this according to your advice.

Thank you once again.

Hi dear,

I am working on the same topic for different regions on west coast. DO you mind if you share your input files and some guides? I have obtained reasonable results using only T2D and fortran file meteo for wind and atm pressure.
