Hello all,

Here is a little survey for you Telemac3D users.

1. Do you use Blue Kenue to post-process Telemac3D SELAFIN files.

2. If NO, were you aware that Blue Kenue provides support for Telemac3D files/data?

3. If YES, what functionality do you feel is lacking in Blue Kenue vis-a-vis Telemac3D.

4. General comments are also welcome.

You can reply here or contact me directly at This email address is being protected from spambots. You need JavaScript enabled to view it.

Cheers... Martin

Hi Serrer,
Apologies but I haven't seen your post until now.
I still use RUBENS to post-process TELEMAC-3D files (of course after slicing them in POSTEL).
I wasn't aware that Blue Kenue does the job. Does it need preprosessing using POSTEL like RUBENS or does it take directly 3D files.

Blue Kenue loads 3D SELAFIN files directly. The 3D prismatic grids can then be visualized and probed in a 2D or 3D view. In a 3D view you can choose to see the grid either as layers or as a volume. Visibility of individual layers can be toggled on or off. ISO surface rendering is available and controlled via the colour-scale (just like iso-lines in 2D).
There is also a Tool to extract individual 2D layers.
From my perspective the one big feature missing is the ability to extract a vertical slice (as others have pointed out in private correspondence). What I will say here is that our approach to this problem was going to be a bit more general. We envisage a tool that will allow the user to define an arbitrary 3D surface and map scalar or vector quantities to it. A vertical slice is simply a particular instance of such a 3D surface.

I didn't list any of the 3D capabilities in my original post because I didn't want to steer the discussion in any particular direction.

Thanks for the feedback (and keep it coming)... Martin

Hello,

Yes, I do use BlueKenue as a pre/post processor of Telemac system, and I find it small but powerful.

The only shortage of BK,I think, lies in its manual which has missed many important instructions of BK. That's why there're so many simple questions on BK in this forum...

Best regard!

Hello Serrer,

I also use BlueKenue as the main pre and post processor of the Telemac system. In my opinion, its advantage is situated in its simplicity to use, while on the other hand it offers a lot of possibilities. Especially as a preprocessor it is in my opinion quite complete.

I also have a question concerning the possibilities of BlueKenue and Telemac3D. When using Telemac2D it is possible to make a Selafin file in BlueKenue that can be used as an initial condition. I use this often when for example I have some measurments of salinity throughout the domain to make an initial condition file (by inter- and extrapolating of the data). BlueKeneu really offers the possibility to do this in an easy way. I was wondering whether it is also possible to do this in Telemac3D: can you make a file in BlueKenue that can be used as an initial condition file? Thank you for your answer!

Best regards,
Stefaan

Hi Stefaan,

At this time, BlueKenue cannot create a 3D selafin file.

Perhaps Sebastien Bourban can give hints how he creates 3D initial conditions files... He is a quite heavy BlueKenue and Telemac3D user.

Cheers... Martin

Hello,

There is no easy way. The best way I would suggest is to use TELEMAC-3D with zero iterations -- you can read in a 2D file as a continuation, geometry or otherwise adding variables to your file for support when you do your calculations.

Then all happen in CONDIM (for instance) where to program your 3D initial conditions. If you use PRIVE variables, you can use the letters O,P,N, (for instance) to print your new variable, or simply re-calculate any of the default variables, which are going to be printed then as initial conditions for your next simulation.

Hope this helps.

Sébastien.

Hello Martin,

... you probably still have some of my wish-list of things on your board ... ;)

To answer your questions:

1.- YES but not Blue Kenue exclusively anymore

2.- ParaView, which is scriptable python and allow calls to redraw of state (ews like) to create a picture without opening the application, using pvpython.

3.- A few things in order or priority:
- display of vertical cross-section along a 2D line as 2D view (disconnected z,x axis)
- calculator
- mapping on a cube-grid (much like the mapping you have of time varying 2D-vectors on a 2D grid)

4.- python scriptable and call from the outside is my highest priority. Fixing the mesh generator for "proximity density" and variable resampling of boundary and soft lines my next priority, although we now have a series of python scripts to do these things ...

Hope you had a good holiday (on your boat I presume).

Kind regards,

Sebastien.

Hi Sebastien,

Thanks for the reply.

Seems to me that a tool to prepare initial conditions for Telemac3D is an opportunity.

Yes, the other items in your list are still on the list.

We've made some headway with building a python interface to the core EnSim library but the usual caveats apply :-(

Cheers... Martin

Hi Serrer,

I asked a question early on this summer about which post processor to use when willing to draw cross sections out of 3D result files.
You mentionned that it was an idea under development for a next Blue Kenue release.

Do you have more information about this ?

Thank you in advance,
PL
