Caelinux discretizer front end to openfoam
In the name of Allah, Peace and Prayers upon prophet Mohamed and all prophets
Dear colleagues, I was working with caelinux discretizer frontend to openfoam. However, I have some problems: 1. There are two discretizer programs in the applications menu, I don't really know the difference between them. 2. The first discretizer worked fine when I tried tutorial, however, even when I change the solver I enter, in the terminal the solver is always displayed as simpleFoam, regardless of what I enter 3. Also, I have complete cases from chalmers university site. When I open the run dialogue in discretizer and input their path, I get fatal error, cannot open folder message I hope any one can help me. I am trying to encourage my students to use opensource, especially, that at our university, we really have no budget to buy commercial equivalents like COMSOL and fluent |
Greetings Abouelseoud and welcome to the forum!

And like I've said before, both aren't fully developed tools, so you will probably find various capabilities that are still very limited :( Quote:

Dear wyldckat, Than kyou very much for your reply. I'll try to follow your remarks carefully and keep you informed with our progress of using OpenFOAM at our university. I think you're right with discretizer not being fully developed and I do believe that since the tutorial worked well, that most probably the errors that resulted with other applications were due to bugs. We'll try to get around them or work from the OpenFOAM terminal. Quote:

Hi there
Bjorn (sp) the developer has updated the software, and it seems better, I have used it to run simple meshes in simplefoam. the developer has a Gmail account and is very good at replying to questions kind regards Stephen |

I would like to thank you all for your comments and concern. They really encouraged me not to give up. I thank God for that. Things are getting some what better. I've tried to help my students by making educational videos of what I learnt with both openFoam and code_saturne. I 'll quote the links to them , may be they may be helpful to some of your students. The comments are in Arabic. However, the video is clear with out comments. Of course , we are still learning and I am not quite satisfied with results accuracy yet, though they are some what reasonable. Also, I may be making some mistakes because I am working fast but at least I hope that these videos will save others "the 4 months I had to spend on getting things work" .

Dear colleague, You can enter the air-foil points as wire points in SALOME and let it drawn inside a larger rectangle. Use "cut" then to cut out the foil from inside the rectangle. Then use extrude to extrude the whole geometry in the third dimension perpendicular to the foil plane. I know the problem is 2D but both openFoam and saturne entitle you to extrude 2D problems with very small thickness because they cannot handle 2D problem. This is very similar to the video forAllah_Salome_draw_mesh, however, the foil will be in place of the circle. When you finish, use the airfoil tutorial in openFoam to know how to define the boundary conditions. The video forAllah_drag_openFoam_saturne tells you how the mesh can be exported to openFoam. I've asked the same assignment from 2 of my students. You may email them to see how they progressed with it. ( ali_alex_and@yahoo.com, eslam_699@hotmail.com) I'll try with it myself and as soon as I get any progress, I'll keep you informed. God be with you and help you. |

Dear colleague, Could you either attach the files here or send them to my son (student) eslam at eslam_699@hotmail.com. He will give them to me. Just tell him that Dr. Abouelseoud told you to post these files so that we can help you figure out what the problem is. |

i already sent an email with the same contents to ur student with the files any way here is the link of my files https://rapidshare.com/files/287119923/airfoil3.zip and the geometric & mesh file is https://rapidshare.com/files/855940017/FFA_24_Mesh.hdf thank u |
In the name of Allah the most merciful and gracious . Peace and Prayers upon prophet Mohamed and all prophets
Dear colleague, in the file airfoil3/system/fvSolution just replace SIMPLE { nNonOrthogonalCorrectors 0; } by SIMPLE { nNonOrthogonalCorrectors 0; pRefCell 0; pRefValue 0; } My experience with discretizer is that the exported case folder often needs editing, so when I get an error message I just search in the openFoam tutorial folder with the keyword that appeared in the message(here pRefCell) to know how to correct it. In this case, I found the correction in the airfoil2D tutorial in (/tutorials/incompressible/simpleFoam/airfoil2D) However, when I corrected this mistake I still got an error because openFoam sees the mesh as not 2D. Please try to remesh but this time make the thickness in the third dimension one cell only. I hope this helps. I 'll try to take a look at the geometry and mesh files. I didn't notice them when I logged in yesterday. |
hi
it's already 1 cell in the third direction i used Netgen 1D-2D-3D for meshing is that right or i suppose to use another method thanks |
In the name of Allah the most merciful and gracious . Peace and Prayers upon prophet Mohamed and all prophets
Dear colleague, If you opened the Mesh_1.unv you sent me with a text editor like gedit, you will find that the mesh is not one cell thick in the third dimension (there are several coordinates in the third dimension not just 2 values). To overcome this do this: Define edge groups over cut_1 for inlet,outlet, upper, bottom , wall .. Use Netgen 1D-2D to generate a mesh for cut_1 Use create groups from geometry to import the edge groups you created. You will find that they appear with _extruded added to their names. in the mesh module in the modifications menu, choose extrude mesh and make sure that you choose 1 step and that the generate groups is ticked. (I found these steps at: http://www.salome-platform.org/forum...10/thread_3005 ) In the preferences in the file menu in Salome, make sure that automatically generate groups is ticked. export the mesh to med (these last two steps are necessary because with out them the extruded groups will not appear in the discretizer) open the med file in from gmsh and save it as unv mesh file. Now if you open it with an editor you will find it is trully 1 cell thick (the 3rd coordinate is either 0 or 1). However, I still get the same openFoam error that the mesh is 3D. --> FOAM FATAL ERROR: This mesh contains patches of type empty but is not 1D or 2D by virtue of the fact that the number of faces of this empty patch is not divisible by the number of cells. From function emptyFvPatchField<Type>::updateCoeffs() in file fields/fvPatchFields/constraint/empty/emptyFvPatchField.C at line 150. FOAM exiting I am willing to give it a second try by next friday ISA because this week is very busy for us because we are preparing some conference work. In order not to be delaying you, my attempt and some snapshots showing the choices in Salome are at: http://www.islamup.com/download.php?id=125906 http://www.islamup.com/download.php?id=125907 If there is any problem with downloading the files just tell me. My mesh in the salome study is Mesh_3 |
thank u for time i'll try and hopefully it works
see u |

In the name of Allah the most merciful and gracious . Peace and Prayers upon prophet Mohamed and all prophets
Dear colleague, You are always very welcome to ask. I just hope you would forgive me for not having time to work on it and give it a second try before next friday. For now, I'm really not familiar with running cases to the end with discretizer. I just use it to import the mesh to Foam constant folder and all the rest I edit manually because with my Caelinux2010, it appears discretizer has several bugs. Consider mailing the correct mesh with the error message that appeared to the person who developed discretizer. He responds to emails and I am sure he is eager to recover from any bugs with his program. His email is bjorn.bergqvist@gmail.com It would be great , if he would help us overcome discretizer bugs. This would make things easier to many openFoam users. |

And I just wonder if there is a tutorial video to do as u doing with the mesh specially with complex shapes and 2d problems Bye |

Dear colleague, I just want to apologize for not giving it a second try on Friday as I promised. It's just that just after I promised to try to help again a few days later one of my sons died. I still am not able to concentrate well on anything, so please forgive me. |

thank you for ur effort
i just wanna know what is the meaning of ANN theory |
Quote:
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 |

Videos and their comprehensibility
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 |
In the name of Allah, the most merciful and gracious. Peace upon prophet Mohamed and all prophets
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.

reliability and risk analysis
In the name of Allah, the most merciful and gracious. Peace upon prophet Mohamed and all prophets
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 Here are the links: openturns forAllah_edu_OT.7z (241.13 MB) http://www.multiupload.com/PIOSLDOCN1 http://www.mlfnt.com/do.php?id=575887 http://www.mlfnt.com/do.php?id=576099 http://www.mlfnt.com/do.php?id=576326 forAllah_edu_OT_2.7z (41.59 MB) http://www.multiupload.com/OFCAX3YEAZ http://www.mlfnt.com/do.php?id=586739 forAllah_openturns_aster_a.7z (83.11 MB) http://www.multiupload.com/RW11NTMKPB http://www.mlfnt.com/do.php?id=592792 forAllah_openturns_aster_b.7z (118.61 MB) http://www.multiupload.com/ZI1T4KBCH7 http://www.mlfnt.com/do.php?id=593355 http://www.mlfnt.com/do.php?id=593378 forAllah_openturns_aster_c.7z (132.82 MB) http://www.multiupload.com/QZU0YW1S12 http://www.mlfnt.com/do.php?id=593409 http://www.mlfnt.com/do.php?id=593510 openturns_scilab_optimization forAllah_optimization_openturns_scilab.7z (421.26 MB) http://www.multiupload.com/7UMLILWTIO http://www.mlfnt.com/do.php?id=610610 http://www.mlfnt.com/do.php?id=611232 http://www.mlfnt.com/do.php?id=612004 http://www.mlfnt.com/do.php?id=612143 http://www.mlfnt.com/do.php?id=612187 God bless you all.

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: http://www.hydroniumion.de/allgemein...mesh-tutorial/ http://www.hydroniumion.de/studium/s...torial-part-2/ http://www.openfoam.com/docs/user/snappyHexMesh.php http://openfoamwiki.net/index.php/Ma...Examples/2DsHM (this last is related to tutorial http://repo.or.cz/w/OpenFOAM-1.6.x.g...3085795470.zip) |
Thank u for ur advise I'll try ur way
