Learning Gambit/Fluent CFD

  1. Jan 13, 2007 #1
    Hi, can anyone recommend me any site/books that could help me to learn the Gambit/Fluent software. Btw, what is the difference between these 2 softwares??
    I am a beginner, totally alien to these softwares and I have about a month to learn it.
    Thanks alot.

    Gambit is a mesh generator, and Fluent a flow solver. You first use Gambit to make a discretization of flow domain, and then Fluent to solve the flow in it.

    Never used these personally, but a colleague of mine once pointed me to this link as nice set of beginner's tutorials:

    http://instruct1.cit.cornell.edu/courses/fluent/

    A month is not a good time. There is a strong junk-in-junk-out tendency with CFD software: if you have no experience, you don't know whether what you are giving it makes any sense, and you don't know whether the results it gives you back make any sense.

    It is good if there is someone experienced around to check your inputs and outputs while you are working out the problems, for months probably.

    Doubtless the best sources are the in built tutorials of Fluent and Gambit that come with the cd's. They have a collection of great exercises using all the important features.

    How can I get the vertices of the NACA0015 profile for designing it in Gambit? Can u tell me the detailed way of doing so??

    is it possible do the flow problem using ansys instead of fluent...

    hi..u can use many other softwares...u cn use ANSYS CFX...
    not sure about this but matlab can also be used i guess

    Hello,
    Is there any CFD for Catia V5 R18??

    doubt

    is it possible to use proe to send design to fluent if so how

    hello, am israa working in my final project using cfd fluent ;
    but am having trouble in exporting the mesh from gambit to fluent 6 because as the error written in gambit " face (no) has ahigher order element & cannot be exported to fluent5"

    if any one knows how can solve this problem please reply.................

    I think (but i'm not sure) that you export 2d for 3d elements. That's my first guess

    Re: doubt

    If you draw your geometry in PRO-E you need to import it into GAMBIT great your mesh and then you can use it in PRO-E.

    In order to do that you need to:
    1. Draw your geometry
    2. Save it in your working directory
    3. Then File -> Save a copy -> select the drop down menu and select .igs extension and save it.
    4. Open GAMBIT then File -> Import -> select the required document.

    hi..
    to all freinds
    i want to know about PRO/ENGINEERS ,i want to draw geometry of ESP in pro/E,
    is it possible to draw in pro/e,i am doing project on ESP performance,

    hi,
    i am doing a simulation of 3D problem.i want to draw it cylindrical coordinate sysyem(r,z, o).but gambit shows X , Y , Z Coordinate . how to do in cylindrical co ordinate , will it show r, z and o axis ?
    i opened the Tools command button then i changed the co ordinated system to cylindrical and I acctivé it . but it still at cartesien coordinate

    please reply

    Hi,
    I want to generate a mesh file by myself in a format the same as GAMBIT out put file, to use in Fluent. I face to this problem that I don't know how Gambit count the Elements, I mean how Gambit count an Element as Element no. 1 or 2 or 50. I generate meshes but I don't know which Element is number 1 or 2 or....
    and if there is a manual that explain different lines of Gambit output file that shows the points coordination and Points of an elements.
    I would be thankful for your nice help

    Gambit software is use for CFD flow analysis.It is application software software use for CFD.But i do not know so much about fluent software.Can anyone provide more information about this.How is these software related to CFD trading?

    Hi,
    I am a beginner and still learning to use gambit and fluent for my project. I am trying to model dispersion of gas from a pipeline. So I created a horizontal cylinder with a vertical cylinder on top of it to represent a hole. Then I subtract that vertical cylinder from the 1st cylinder. Then I try to do the meshing. I thought that it could work just like that. But it seems like I miss some steps but I don't know what is it. Please help me. Your kind help is greatly appreciated. Thank you in advance.
