    Dear Laurent,

    could you please describe the error in more detail.
    Which settings did you use, and does that change anything about the error?

    Best,
    Fabian

    Thanks for reporting! We have fixed that minor bug and we will release the fix in the next release. Meanwhile, please run the code only with as much cores as you have physically available in your system!

    Hi Everybody,

    Today with the update of Ubuntu 18.04lts
    example/laminar/cylinder2d” with MPI will works fine!

    DO entirely compile olb1.3 and cylinder2d.
    So I have a doubt about the code correction…
    (because it’s the same olb1.3 release that last time for me…)

    Laurent.
