    Useful LES tools in Fluent - Part 4

    I don't know if i understood correctly what you mean by two-way periodicity.

    If you mean to make the copied section aware of the main domain where it is copied, then it is not possible and does not make sense, because the copied section already has all the information it requires. You could instead simply define the copied section to be in the domain and not out of it (as some OpenFoamers use to do), but my experience is that such coupling is only detrimental to the stability.

    If instead you mean to apply it between multiple couples of faces, then you can simply compile different versions of the UDF, one for each couple of faces.

    You have 3 options:

    1) Open it with wordpad
    2) Open it under Linux
    3) Do "unix2dos remap_par.c" in a linux shell, then use it under windows

    Useful LES tools in Fluent - Part 4

    Hi!

    Thank you for this work - it seems very interesting, and it could help me with my simulations. When I download the text file, however, the entire code appears as one big chunck of text. Could you maybe reupload the text file, where the code can be better understood or can you maybe just post the code somewhere on this website?

    Thanks in advance for your help!
