Wrong pressure output. Correct BC for U and p?

Hi FOAMers,
I try to simulate a wing flying in the air using potentialFoam (I assume I have to use it if I want to run a simple Euler run?!). I did have a look at the tutorials for the motorbike and 2dmoving wing in order to get the BCs right. However I am still not entirely sure about the BCs (see attachment) in the 0/p and 0/U file as the results I am getting are funny. Especially for p which ranges from 0 to 1e-16. Hope someone can help me out. |

potentialFoam doesn't change the pressure.
"p which ranges from 0 to 1e-16" - it's simply ParaView try to make a map with some range for you, that's why it give you another value for pressure like 1e-16. the task of potentialFoam is to define the internal field for velocity. So if you see the results of the potentialFoam you can find that you have now a non-uniform internal field with a lot of values inside |

thank you very much for your help! I ran it with k-omega now and I get proper results!
