[GMSH Aster Tutorial] Solving a Gmsh Model with Code_Aster (Groups, Mesh Format, Solver)

Ғылым және технология

Gmsh is an open source 3D finite element mesh generator with a built-in CAD engine and post-processor. Its design goal is to provide a fast, light and user-friendly meshing tool with parametric input and advanced visualization capabilities. Gmsh is built around four modules: geometry, mesh, solver and post-processing.

    God bless you for these tutorials, Sir! It is your channel that largely helped making a transition to open source CAE for my work and phd study! I can’t thank you enough 👏 👏👏👏

    Thank you very much teacher. Is it possible to make a model of a concrete beam attached to an iron plate from the bottom?

    Hi, I have a doubt in doing the analysis of a shell model in Code_aster. While assigning the local axis of a shell member using "ANGL_REP/VECTOR", should we need to apply the local axis for all the shell members in the model.

    the unv files from your github don't have any mesh in it, when i use it, aster write : "no system of coordinated is defined "...

    Hi Cyprien, Great tutorial. I tested this with code aster version 14.4 and gmsh version 4.8.4 and it works. I can access the physical groups for line and surface in my comm file. However, when I add physical points I am unable to access these using the unv file format. Have you experienced this? If so, how did you solve it? Best regards Torgrim

    Have you tried to export everything in the unv (not just the physical groups) ?

    @@Feaforall hi cyprien, and thank you for your quick response. Yes, I have. I should also mention that I am running this on a windows machine. So, I am using a script to create the geometry. I then meshes it and exports it in gmsh. The physical groups for lines and surface is picked up by code aster, but not the point. I also tried to do this with the med file format, and this works for gmsh version 4.1, but not for gmsh version 4.8.4.

    Hi Cyprien, do you intend to do it with SalomeMeca as well?

    Why? With Salome Meca, it’s even easier… just import the mesh in the smesh module and then import the comm file in aster study and run aster.

    Hi! Could you make a tutorial using gmsh to generate the mesh from the openFoam "damBreak" tutorial? I tried to build the mesh by openCASCADE, but when generating the volume gmsh suddenly closes. I do not know the reason. Thanks!!!

    Double check the Gmsh version you have. Maybe it’s too recent and the Gmsh file is an old version.

    @@Feaforall Thanks for answering! Doing it through windows, I was able to add the physical groups (volume). In ubunto (ubunto 22.04 lts), when I opened the physical "volume" groups, gmsh suddenly closed. The gmsh version is 4.10.5. Thank you very much!

    it's possible used mesh created with GMSH in OpenFoam?

    Sure, you can generate the mesh in UNV format, and OpenFoam has a converter to transform unv in openfoam format. I have a video on how to use Salome with OpenFoam in which I show that. It’s exactly the same way, watch that video
