TOPIC: temporal and spacial different wind in telemac3d

temporal and spacial different wind in telemac3d 7 years 10 months ago #24797

yuanhui	Hi all, I am trying to include the temporal and spacial different wind into telemac3d, and I modified the meteo.f subroutine and prepared the meteorologic data file following the telemac2d example wind_txy, but I realized in v7p0 telemac3d version, there is no keyword OPTION FOR WIND, then how can I tell model that I want wind to be temporal and spacial different? Thanks a lot!

aleroy	Hello, The option for space-time varying wind OPTION FOR WIND is only available in the latest release of TELEMAC: V7P2. It is available for download. If you want to stick to V7P0 you will have to use the modified METEO subroutine available in examples/telemac2d/wind_txy/t2d_wind_txy.f Best regards, Agnès

huyquangtran OFFLINE Expert Boarder Posts: 271 Thank you received: 23	Hi Agnès, I suspect that my 3D model has a problem with reading the wind file as I use a sample t2d_wind_txy.f from my previous succesful model (2D model) running on V7p1. If some keywords used for wind data have been changed, I think I should find TELEMAC3D V7p2 operational manual to read. Has the manual been released? Thanks & Best Regards Huy

Hi there,

My answer was not very clear the first time I'm afraid: the keyword
OPTION FOR WIND has existed for a long time in TELEMAC-3D
but the value 3 for it, which means time-space varying wind, was only available when using a user fortran meteo file until V7P2.
In V7P2 it is now possible to use OPTION FOR WIND: 3 and provide a binary wind file for time-space varying wind.

In your case, for time-varying wind only, you should use OPTION FOR WIND: 2
and use an ascii file similar to: examples/telemac2d/wind/fo1_wind.

I hope this helps.
Best regards

Agnès

aleroy	Hi, It's not available for download on the website yet, but I think it should come as pdf files in each module documentation folder when you download the svn repository of the tagged version V7P2. Cheers, Agnès

My experience with 7.0.1 differs somewhat. I had an error thrown because OPTION FOR WIND was missing, as it actually was. I just had to ad it to the cas file to get it going, as per the manual (Sec 6.3.1).

A description of all keywords and the permitted specifications can be found in the ASCII file <your telemac directory>/source/telemac2d/telemac2d.dico. There I read

NOM = 'OPTION DU VENT'
NOM1 = 'OPTION FOR WIND'
TYPE = ENTIER
INDEX = 94
MNEMO = 'OPTWIND'
TAILLE = 1
DEFAUT = 0
DEFAUT1 = 0
RUBRIQUE = 'EQUATIONS, SOURCES'
RUBRIQUE1 = 'EQUATIONS, SOURCES'
NIVEAU = 1
AIDE = 'donne les options pour introduire le vent:
0: pas de vent (enleve le mot cle VENT (logique))
1: constant en temps et en espace (donne par le mot cle
VITESSE ET DIRECTION DU VENT)
2: variable en temps donne par fichier formate
3: variable en temps et en espace donne par fichier formate'
AIDE1 = 'gives option for managing the wind:
0: no wind (we can remove keyword WIND (boolean))
1: constant in time and space, given by keyword SPPED AND
DIRECTION OF WIND
2: variable in time and (constant in space), given by formated file
3: variable in time and space'

These descriptions might be closer to the facts than the manual, I have been presuming so far.
Hope this helps.

yuanhui	Hi, Thanks for the reply. I added 'OPTION FOR WIND=3'to the cas file, as attached, but when I opened cas file in fudda-prepro, there is the error. Will this cause problems when I run the cas file? Thanks Yuan Attachments: OPTIONFORWIND.png (24KB) ERROR.png (16KB)

Watermotion.eu	From the first snapshot I cannot see the assignment 'WIND = YES', but it may well be anywhere else in the cas file. Check it out first. Else, I pass.
