open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi all,

I thought I'd share my master's thesis (in French), published a few months ago, on the use of GAIA for modelling gravel bedload evolution in a mesoscale flume. Perhaps some of the discussion could be relevant either to end users looking to model bedload processes, or to the GAIA team for potential improvements.

It must be said, I'm not a natural academic, and I'm sure there are many ways I could've improved my work, but I had to teach myself many of the tools to do any of this. That said, please let me know if there are things I could take into account to improve my modelling in the future.

I may as well take this opportunity to thank the kind folks on this forum who helped me with technical questions throughout my studies.

Bonne lecture !

Hello André,

Thanks for having shared your master's thesis.

What do you plan to do now? Still in modelling with TELEMAC tools?

Bonne continuation,

Chi-Tuan

Hi Chi-Tuan,

I'm working in consulting engineering now. I still use TELEMAC on occasion, but not as much as I would like. HEC-RAS is more common here. Nevertheless, a lot of what I learned in my studies is transferrable, even if only as general knowledge in sediment and hydrodynamic modelling.

Bonne journée !

Hi André
Maybe you could update your profile as for us you're still a student of Sherbrooke university ...

Bonne journée

Maybe you or an admin could update the profile interface to remove SISYPHE, add GAIA, and remove Windows XP as an option, and then we can talk about me updating my profile ... bonne journée

Well seen! 1 point for you!
For sure this is something to update...
But sorry I'm not able to access to the back-end of the website to upgrade this.
By the way, those changes must be decided at the consortium level (in which I am no longer )

Hello，
I am currently learning to use TELEMAC and GAIA coupled hydrodynamic and sediment numerical simulation. I was extremely honored to read your excellent paper titled "Modélisation numérique de la formation d’une couche de pavage dans une rivière expérimentale novatrice". Your research findings have not only provided me with valuable academic inspiration but have also greatly broadened my research horizons. For this, I express my sincere gratitude.
While using the V8P4 version of TELEMAC and GAIA, I have encountered some challenges. I sought help on the official remote communication forum, but unfortunately, I did not receive any satisfactory responses. Overcoming these challenges is crucial for deepening my understanding and advancing my research. Given your profound expertise and insights in this field, I eagerly look forward to your valuable guidance. I have prepared a document detailing these issues; may I ask you a few questions?
Best wishes,
Abandoned

Hello Abandoned,

Thank you for the kind words, although I fear you are overestimating my proficiency with openTELEMAC. I haven't used OTM much since I finished writing my thesis in October 2023, and I have hardly used GAIA since then.

I honestly don't think I have the time or means to help you with your questions directly. I am out of the academic system and no longer use openTELEMAC enough to act as support. That said, if you post them on the appropriate forum here, and show what you have tried in furthering your understanding of OTM, then I and others will be happy to help. Here is some of my advice:

In my experience, if one takes the time to define questions clearly (citing the end goal, for instance) and detail what has been tried so far, people are more likely to respond and help. You can see from my post history that I had many questions for the development team during my thesis, and here is how I approached posting.
I took the time to detail both my immediate goals and the motivation behind them, so that users trying to help me could see whether I was asking the right questions to begin with, while also having concrete questions to answer.
Likewise, writing out what I had tried so far allowed people to see that I was doing my own homework, helped rule out obvious solutions, and allowed me to see other solutions I had not tried yet. More than once, I would write out a post, realize that I hadn't tried something else yet, thereby answering my own question.
Citing questions from the documentation and/or the source is also a good way to show that you have attempted research. openTELEMAC is not an easy system to learn, and while I learned the basics from a tutorial, I had to learn much of the details myself or by asking specific questions, here or to my professors.

Kind regards, and best wishes,
André Renault

Hello André Renault,
Firstly, thank you for your honesty and valuable advice.
I indeed have some questions about certain aspects of openTELEMAC, and I appreciate the suggestion to seek help on the forum. I will follow your advice and clearly define my questions, detailing the solutions I have already tried. I will make sure to include my end goals and the steps I have taken to reach them in my posts.
I will also refer to the documentation and source code when posing my questions to demonstrate that I have conducted preliminary research work. As you mentioned, openTELEMAC is a complex system, and I am aware that learning and mastering it requires time and effort.
I will post my questions on the forum as soon as possible and will be keeping a close eye on it, hoping to receive guidance from you and other experienced users. Once again, thank you for your support and understanding, and I look forward to engaging with you and other community members on the forum.
Best regards,
Abandoned
