Hello Users~!
I want to solve the external flow around 2D airfoil in subsonic area. In this case, the segrated solver for the problem was chosen and incompressible ideal-gas was used as a material. For boundary condition, I'm supposed to apply the pressure-farfield to the far-field. But Flent gave the warning signal that said the pressure-farfield cannot use with incompressible-farfield. Then how can i handle the far-field boundary on C region of C grid type in the subsonic flow. Share your knowledge. Thanks. |

hello
it is better to use coupled solver of fluent because it is better for pressure far field boundary condition. |

Dear Greeneye
As i mentioned before, the flow problem is of subsonic regime. Actually the flow velocity is 30m/s. I understood that in a subsonic flow i've to use the segrated solver based on pressure. Does it matter that i use the coupled solver for the subsonic flow? |
