Star-CD and BC.
Hi,
Since I am just starting to use Star-CD, I would very much like to know how the turbulent boundary condition are applied in Star. Ex. simple case: I have a 2d channel with a square cylinder in the middle of the channel. ------------------------------- ---- Inlet -> | | Outlet -> ---- ------------------------------- Since the inlet and outlet are easy to specify and also the top and bottom walls of the channel (= no-slip). (implicitly) But what about the square cylinder in the middle of the channel ? The grid in the channel was generated using the simple a block geometry with a uniform grid. And the cells within the square cylinder was then deleted from the cell set. Does I also have to put no-slip wall definitions onto the square cylinder walls or are these wall defined the same way as the walls of the channel ??? Thanks in advance. Regards Roued |
Re: Star-CD and BC.
Any unspecified boundary is automatically assigned to region 0, which is by default a no-slip wall.
As your case is 2D, don't forget the symmetry boundaries on the sides. |
