    I m new on OpenFOAM, I prepared a mesh in STAR CCM+ and I am trying to export it to OF. I searched about it and find this ccm26ToFoam. So now I am trying to use it but getting same error. Can anyone help me?

    OpenFOAM-9 is installed on my ubuntu.
    My mesh is tetrahedral with prism layer from STAR CCM+.
    I can export it as .ccm format.
    ccm26ToFoam doesn’t work. (There may be an issue about my installation but I did some analysis before without any problem by using rhoSimpleFoam.)

    Hi Osman,

    What is the error message? can you post it here?

    In my lecture I have proposed to use ccmToFoam mesh_file_name for ESI_variant.

    Could you also try it please.

    You also said that you did analysis before with starccm mesh using OpenFOAM solver. How did you convert that time?

    Thank you

    I was using OpenFOAM-9 before starting to this training. I used fluentMeshToFoam before and solved a case without any problem. So that is what I was talking about.

    Nowadays I was trying to use ccm26ToFoam. I learned it from a discussion on CFD Online. But I switched to OpenFOAM-v2112 after starting to the OpenFOAM training. So now I m using ESI_variant. I have just finished Lesson 4 so I haven’nt seen your lecture about ccmToFoam. But after your answer I searched about it and figured it out. Now I can translate my ccm meshes to foam format without any problem.

    Thank you.

    I m sharing the solution, excuse me if there is something wrong, it worked on my pc.

    download libccmio-2.6.1 to ThirdParty directory.
    Then run these commands:

    ./makeCCMIO libso
    ./makeCCMIO lib

    Hi Osman,

    thank you for your informative details. you will see details mesh conversion techniques in Lecture 9.

    But I am happy that you solved your problem by yourself.
