    Curious in this case if the inflow is axissymmetry, is it possible to simulate only one single passage for better efficiency ?

      Hi sir
      This is Anand M . I'm a final year student of M.E(Aeronautical Engineering).my project is related to wind turbine flow analysis in openfoam.did u get any model simulation please help my project

    Dear Holzmann CFD, is there a way to couple the rotating mesh function with lagrangian particle tracking? Say one of the blades in your video is burning, and the smoke particles are falling off from the tip part of the blade and being carried away to the wake.

    • @HolzmannCFD
      @HolzmannCFD  2 роки тому

      yes. Use some lagrangian solver and inject the parcels/particles on the tip of the blade

    Great job ! I see their is no parallel run, how many time needed to run this tutorial ?

    • @HolzmannCFD
      @HolzmannCFD  4 роки тому +2

      Didń t I add the parallel stuff in the training case? It should be around 3 h on 4 cores. That's why the resolution is not very well. But as a community case, I want to give people access without having a 200 core machine ; )

      @@HolzmannCFD My bad, no parallel computing was for the archived case. You are right for the current community case there are 4 cores.

      I tried to run the case but I get this error : Integration is not defined for scale functions
      It seems to come from the dynamicMeshDict file.
      If you have any idea regarding what could be the root cause ?

      @@jean-yvesfouchecourt7913 Yes, it is related to the fact that I defined this case for the latest DEV release. I guess for the original FOAM 7, it is not working. I will check it.

    Hello, thanks for your video. Did the temperature transport consider the Boussinesq assumption? I am using buoyantBoussinesqPimpleDyMFoam to simulate a fan in a room, it won't work. But if I use pimpleFoam, don't consider the temperature and its effect on body force, it works well. I don't know why.

      No buoyancy effect included in the case presented here.
