meshing a Naca 4412 airfoil - help
hello. Im analysing a Naca4412, and I need some recomendations of the way that I should mesh the rectangle that contains the airfoil (low Re). 1. What kind of face Spacing? (Angular, relative error, constant, volumen spacing ?) 2. If I should create a new Face Space, and refine the mesh around the airfoil or create a control point and refine the mesh ? 3. how can I change the type of the element? and know the dimension, so I can extrude the 2D shape? 4. How many layers in Inflation? what configuration in teh inflation?
Thanks in advanced Santiago. |

Hi,
These parameters depend on many things. Some things to consider are:
These parameters affect both the choice of physics to model and the mesh. Glenn Horrocks |

1. Re=400.000
2. yes. 3. no. 4. no. 5. both. 6. not yet. Do you have a tutorial or paper that specify what kind of mesh do I need? or some kind o guidance? Thanks a lot santiago. |

Hi,
In that case you really only have one option which is to use the transition model in CFX. That has the following implications:
Hope that helps. I think you will find some validation examples of the transitional turbulence model on the CFX-community website. If not your CFX support person should have some. Glenn Horrocks |
