    hi, thank you for the educational video for who at the beginning of the ANSYS fluent, this was so helpful. i have a question if you don't mind. can we use another visualization tool (i mean plane 1 alternatives) in order to view better streamline?

    Hello, after setting my speed according to mach 2 in the inlet in the boundary conditions section, if my rocket is at an altitude of 5000 km, what should I change and where should I do it? The reason I ask is that I cannot come to the thermal section in the inlet in the boundary conditions section and change my temperature.

    hi, thank you for the educational vide of the ANSYS fluent. If i have a compressible flow upto 3 mach and i used pressure farfield and pressure outlet, what are the values of the gauge pressure and temperature. How do I calculate them?

      Hello. This is up to you actually. What is your operating conditions, firstly you should decide it and after that go for standart atmospheric table and check the corresponding values

    Hello dear friend. I have a question about CFD. I am working on a car cfd analysis on ansys. My cd results are normal but my lift coefficient is negative value. İs it normal ? How can fix it ?

    • @cfdbabaopenfoamansyscfd2972
      @cfdbabaopenfoamansyscfd2972  2 роки тому +2

      Lift results can be negative. It shows that downforce is acting on the car and can make it more stable while driving.

    Hi, Thanks for the video. While meshing I got an error : Inflation created stair step meshing at some locations. How can I fix this?

    It was quite helpful . . could u please upload a theoretical lecture on CFD Models like K-epsilon, k omega . . .or refer me some book to understand these models.
    secondly I start the inialization as hybrid . . not standard as u did . . what's difference be two ??

      Hello. I am glad you found the video helpful.
      I can try to upload a theoretical lecture on CFD Models in near future. You can refer to internet articles about people sharing their experiences with different turbulence models to understand their behaviour better. In layman language, I would say k-epsilon model is good at predicting streamflow region whereas k-omega SST model is good at predicting flow near wall boundaries.
      Solving of our CFD equations in an iterative process that requires an initial guess value. We can manually provide initial guess values by using standard initialization or else let the software calculate initial guess values by using hybrid initialization.
      I hope that answers your questions. Keep supporting and share my videos with all your CFD friends.

      Hello. As I mentioned at the start of my video, I received this geometry from one of my subscribers for simulation. You can write to me at cfdbaba@gmail.com if you wish to request this CAD model.

    i keep getting drag force values way higher than I should. Expecting around 45 N but ansys showing a value close to 3 million. any reason you know why this is happening?
