Dear colleagues,
Since some of the links may have expired, we reuploaded them.
We also added some videos related to fluid structure interaction, which is expected to be quite important in advanced boat design. (The new links are at the end of the post. Note that I upload each file to 2 different sites , hoping that atleast one site would be easy for you to download from wherever you are). Hope you find them useful.

Dear colleague,
ANN theory is the the theory of artificial neural networks (ANNs), which are a tool that can be used in ship design. ANNs are mathematical methods for approximating a certain function based on existing data samples. You can train an ANN to take as an input the air foil coordinates and give as output the drag coefficients. (this is prediction) You can train it to take as input the drag coeff. and give as output the coordinates (this is design). The video ANN theory explains in more details.
http://forallahproject.blogspot.com/
contains several papers that use ANNs in design

Dear Abouelseoud,

thank You very much already now for sharing these tutorials! Unfortunately I did not yet have time for watching them, but the topics seem highly interesting, so I certainly will try to follow them!

Up to now I only downloaded the videos connected to salome and openFoam. Could You please tell me, which ones of the other videos are comprehensible (or if that list is shorter - incomprehensible) for non-Arabic-speakers as well?

Moreover: Do You have a list in English, French or German of the research articles Your group published on the artificial neural networks and their use in optimization? While for me that is a thing of mere interest/couriosity, for my thesis adviser they actually might be of real professional interest...

Thank You for Your answers already in advance!

Sincerely,
Bernhard

Dear Bernhard,
Thank you very much for your encouraging message.
First: I don't think the Arabic comments are at all necessary for following the CFD videos, they are self-explanatory with out any comments. The comments were just additional help for my students. If you find any step not clear, please do not hesitate to ask. I admit though for the ANN theory videos, especially, the comments are necessary. I'll try in future videos, God's willing, to include remarks in English as well as in Arabic.

Second: I think these are the most important videos: Only 1,2, 3 and 4 are important to start with :the rest you can watch from them what suits your area of research in the order that is convenient for you:

1. For those not familiar with ubuntu:

2. For those new to openFoam:

4. A complete simple example of Salome/openFoam/code_saturne

Third, the following are links to work our research group published involving ANNs: they are in English

Hope this helps. Thank you very much again for your encouragement

Note: I browse the Internet with out loading pictures(edit-->preference option-->content--> load images automatically is unchecked) and with flashblock (https://addons.mozilla.org/en-US/fir...on/flashblock/), so I would not notice if any of the uploading sites is not respectful enough.

Dear colleagues,
Attached are a set of educational videos related to a very important topic : incorporating uncertainty in engineering design (reliability and risk analysis). The videos illustrate how the following opensource tools can be used to achieve this goal:

openTurns (www.openturns.org), Scilab (www.scilab.org),code_aster under Salome-Meca 2011.1 (http://www.code-aster.org/V2/spip.php?article303), under Caelinux operating system (www.caelinux.org) OR Ubuntu operating system (www.ubuntu.com)

You will find that I upload each video to 2 different sites (multiupload & mlf.net). Since mlf.net only accepts small size files, I zipped each of them as a multivolume archive. To extract such an archive download all its parts to the same folder and then remove the .zip extension from their names so that the last part of the name is the number. By double clicking the first part of an archive then it will be extracted, God's willing.

Later on, God's willing, we will show how we can link openTurns to CFD software like openFoam

Dear friend,



as of i am working on the GUI part of the openfoam so i request you to send the procedure for installing Discretizer in Openfoam2.0.1


thanking you in advance

Hi
I hope u feel well
I'm trying to generate mesh for open foam and I've tried salome meca, netgen, and gmsh all of these software faild because I import 3D model from solid works (step extension) but when I generate mesh there is always a surface which has a singular matrix and mesh generation will be failed so can anyone help me in this issue
Thanks

Dear colleague,
I would recommend that u export your geometry as stl file and use snappyHexMesh. I really feel that when we use other software than built openfoam utilities for mesh generation , we really waste too much time and effort over meaningless bugs: we just waste our time and effort and even if we get around the bugs we find we learn nothing and gain no experience when we correct them because they are just bugs: we spend long times trying to make things work while there is really no problem with our understanding of the underlying concepts. This was the case for us with our work, so please try these:
