open TELEMAC-MASCARET The mathematically superior suite of solvers

Hello !

No news from my problem of fetch ??
Thanks a lot

Hello,

Sorry, but this week I am out of office most of the time and I do not have time to check and run your model.
Have you tried, as I suggested you, the linear wave growth term in the version V6P1 of TOMAWAC ?

I'll give you a more detailed answer asap.

Kind regards,

Giovanni

Hello,

I took a look at your model.
You can improve your results by changing the wave growth limiter model used in TOMAWAC (keyword: WAVE GROWTH LIMITER). The default value of the keyword in the versions V6P0 and V6P1 is 1, which corresponds to the criterion proposed by the WAM group (1988). If you set the value of the keyword to 2 you get better results (larger Hm0 values, I tested it on your model). The value 2 corresponds to the criterion proposed by Hersbach and Janssen (1999).

If you add also the linear wave growth source term (keyword LINEAR WAVE GROWTH) available in the version V6P1, you get even better results.
I tested your model setting the steering file as follows:
WAVE GROWTH LIMITER =2
LINEAR WAVE GROWTH = 1

and I obtained Hm0 values larger then 1m.

Hope it helps
Kind regards,

Giovanni

hello

I have dowloaded the new version of telemacsystem, to be able solve my problem of fectch. The problem is that when I launch a tomawac case with "croissance linéaire des vagues = 1", it says that it doesn't exist in the dictionnary file. Have I to create a wind formatted file ? I just want to generate a stationnary wind.

thanks a lot !

Hi
Did you use fudaa to manage the creation of steering file (this allow you to avoid error on the keyword).
I chack in version 6.1, CROISSANCE LINEAIRE DES VAGUES exists so you shouldn't have this message if you don't make any error in the letters or space in the keyword.

For me there is no relation with the wind formatted file

Hope this helps

I used fudaa to create the steering file, it is strange that it doesn't work, could it be a pb of language (it is in french)?

in the dico file I haven't found the keyword and even in english I don't find it. I attach my dico file, maybe you can add it and send it with the keyword ?


C:\fakepath\tomawacv6p1.dico


thanks a lot

sorry the file is there

Hi
The dictionnary seems to be very different from mine.
Try to use this one


Hope it will works

Regards

hello

The simulation worked with your dico file.

The problem is that the value I obtain is still very low compared to the giovanni results and the bertscheider formula. I should obtain more than a meter at the end of the model, and The result is about 40 cm.

I attached my files.

Thanks !
