Hi
I am using Star ccm+ for a project on flat back airfoils and its just a 2D analysis . How to generate grid using Star ccm + and is there any criteria for creating a fluid domain around the airfoil prior to grid generation? Can anyone please guide me on these issues ? Thank you, Sen |

There are two ways how to obtain a 2D-mesh.
1) Import a real 2D-mesh. 2) Create a 3D-mesh and convert it into a 2D-mesh. But be sure that your 3D-mesh has got the correct position, because CCM+ always convert the XY-plane (Z=0) into a 2D-mesh. Best regards, Max |

Just don't make it too small. Let's say a cylindrical domain with a diameter of at least 10x chord length. Better 20x or 30x. Cells far from the airfoil surface can get pretty large, so that won't have too much impact on the cell count.
