open TELEMAC-MASCARET The mathematically superior suite of solvers

Hello,

I am currently having a look at following particles in my estuary case.
I can't really find an exhaustive description of the method used in T2D and I did not put a hand on the right Fortran file neither.
Does the "Flot subroutine" is equivalent to a "Progressive Vector Plot" or it uses a Lagrangian field ?

I am sorry in advance if the info was obvious.

With best regards,

Alexis

Hello,

Well, the details are in the user manual (hopefully) but basically drogues are like floating bodies and the program follows their trajectory using the capabilities of our subroutines designed for the method of characteristics. The Lagrangian drifts are a bit different, they do not record the full trajectory but give the displacement during e.g. one tide. My PhD student Cedric Goeury, who works on oil spills with particles would be very helpful for details and post-processing, but is currently in the US for congresses and holidays, he will be back at the end of May-early June.
In the flot subroutine you just give times of releases and starting positions. There is if I remember one test-case in the folder test.fr (tentative name "derive", not sure, I am not in office).

Hi Alexis,

The BETA version of BlueKenue I made available to you includes our Lagrangian sediment transport model PSed. You can use this model to simulate the drift of neutrally buoyant particles by adjusting the density and fall velocity parameters of the sediment on the Sediment properties page.

This model uses t3s/t3v files as input. So what you have to do is, load a Selafin file in Blue Kenue and save the velocities to a t3v file and the corresponding depths to a t3s file.

To create a new PSed simulation, choose "File->New->PSed Run..."

I've attached the scientific reference manual for your information.

Cheers... Martin

Accccckkkk for some reason I can't attach the manual here. You can get it from the ftp site at
