open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi community
Is there any example of the use of the FES atlas to model the tides.
any help will be appreciated

Hello Mourad,

You can read the following document (in French):
www.opentelemac.org/index.php/component/...atlantique?Itemid=55
and more particularly the sections about the use of LEGOS-NEA atlas.

You have to built your own "HARMONIC CONSTANTS FILE" from FES-2014 atlas by interpolating each tidal constituents (amplitude and phase for elevation and currents) on your boundary points with the format given in appendix 4.

I hope it helps.

Thank you
I download this file, it is realy useful.
thanks again
Mourad

by the way have you already downloaded and installed the FES20014 softwre for extraction of the tidal harmonics and prediction of tides?

Yes, but I don't use it to make boundary conditions to my models as Telemac-2D computes them by itself ! You just need to provide harmonic constituents at boundary points and Telemac will do the re-composition itself.

Thank you again,
I can extract the amplitude and phase of the tidal level and velocities with matlab. I can then interpolate them at the open-boundaries nodes and run telemac sumulations. However, I went also see how the FES software (wrote in C language) predicts the tides.
But I thin that software is only installable on linux platform not on windows as explained in aviso website. if you have any information avout that, don't hesitate please ton send them to me, cause any remark will be appreciated.
Thank you for your information, actually without them I wasn't able to run telemac with FES data.
Cheers
Mourad

For my part, I use it on Linux. I don't know if you can compile it on windows, sorry.

Hello Mourad,

You can download a "virtual machine" on your windows and install a linux image on it. That should allow you have a linux environment on Windows and allow you see how FES works. That's how I compile FES2014a.

Salut Ekechijioke
Finally the guy in charge of our cluster has installed the fes-lib. On my personal computer I installed the vmware machine and ubuntu, that's realy great, thanks a lot for the links you gave to me.
However, I faced some error at the configuration and compilation of the fes-lib on my personal computer altough I've followed what was demanded in readme ant the install files. Do you have some tips to do it in the right way...may I miss some configurations like variables exports or somethings like that.
May you have a small tuto on how to predict tide with fes-lib?
thanks in advance for any kind of helps
Regards
Mourad

Hello Mourad,

1. I am assuming you have downloaded the FES tide data.

2. Requirements for FES
- utash
- NetCDF
see the file named "Install" for the links to download them.

3. You will then need to build the NetCDF library (without remote client access). You can find the requirements and steps to achieve this here: www.unidata.ucar.edu/software/netcdf/doc...netcdf.html#building

4. Once you have built the NetCDF library in your linux, all that should be left will be adjusting the FES code to get your desired tide prediction.
