that's my problem, the velocity is zero in circles, because it is declared type wall
my question is are there as a condition to limit, so that the velocity is maximum at the center of the pipe? |

Greetings dima13,
It's a bit difficult to understand what is your question really is... Are you looking for a way to impose a parabolic inlet velocity? Best regards, Bruno

nn, I want a condition to limit, on blockMeshDict, which gives a velocity maximum on the wall,
in the wall boundary conditions is of type Wall I am looking for a type so that the velocity is maximum on the wall |

Hi dima13,
Have you tried fixedValue? That way you can prescribe the maximum value on the wall: http://www.openfoam.org/docs/user/boundaries.php Best regards, Bruno
