Boundary conditions on a C mesh

Good morning to everyone,
I have a simple question.. I'm simulating a flow over an airfoil with a "C mesh", and I was thinking about this: in such a mesh i believe that the "inlet" is made up of the C itself plus the top and the bottom, while the outlet is only the remaining patch on the right. But now I'm in doubts if I'm doing the right things.. Can anyone help me? Thanks Simone |

Dear Simone,
the answer to your question depends on whether you have an inclined flow or a flow parallel to the skeleton line for the inclined flow:
for a flow parallel to the skeleton line:

Well, my flow is entering the domain from the "C" which is on the left, with the inclined airfoil..so I have to change my boundary conditions because they were wrong! It has sense that the flow enter "from the C" right? I don't have to split it right?
Thanks Colin |

As you mentioned the second description matches to your case, thats right.
I have to note that I was assuming that the flow is coming from the right side with the C part on the right side as well, (sry I used shipbuilding standards on my foils so everything is little bit different). so you have to turn around everything I said. regards Colin |

Ok so..with my "C" on the left, inclined flow, and flow entering from the left I define the "C" and the lower part as inlet right, while the top and the vertical patch on the right form the outlet?
