    Cfd Forces (car analysis) Begginer No experience

    Caslor Zach

      I would like some help about understand witch forces needing for a car cfd

       

      ( i have seen one tutorial before some time with a rectangular car but cant spot it any more)

       

       

       

      Lets say that this will be the car   ( i want to start with simple shapes to understand first how all this work )test erotisi.jpg

       

       

       

      it is pointing to the Z axis

       

       

       

       

      I run the cfd wizart ( the station i am working find that has cfd simulation installed ) and then i place the right units that  want

       


      next this

      After that i choose air as the fluid

      And after i place the  speed that i want to have  ( i discovered that if i have positiv speed the air traveles from the back in my analysis... but if i place negative speed -100khm then the air comes from the front where i want my shape to travel )

      After few more steps and finishing wizard..  i remember from the tutorial that i had seen that had to place some Global Goals

       

      i choose the velocity Z

      test erotisi6.jpg

      (this is the tablet of the forces that apears in global goals panel )

       

       

       

      but what forces is for the presure in the object...   the drag and lift of the car ?

       

      all the forces in Y axis ? (this is the axis point upwards )

       

       

       

       


      Thanks in advance for your time

       

       

       

       

       

      Ps: I know that this is something so simple and lot of more (physics and maths) had to envolve for serious cfd car analysis... but i am asking something basic  based in solidworks ready configurations
