the internalField entry of U file is not valid in pisoFoam

i was solving a 3-D cylinder flow case with pisoFoam.
the internalField entry of 0/U file was set to uniform (1 0 0). however, the preview of 0s showed that the internalField entry failed to work. the U value of internalField remained to (0 0 0), see the figure below. Attachment 26973 boundary Code:

Hi,
did you check if your boundaries are correct. It seems that inlet and outlet are not the patches you wanted to have. |

My computational domain is a circular cylinder. Inlet patch is on the left hand, and outlet patch is on the other side. Is there anything wrong about the boundary condition? The similar geometry was used in a 2-D case with icoFoam. And internalField entry of U file worked. shuoxue |
Do you have another file in 0/ which has the "object U" entry? E.g. a file U.org?
Note that since you are looking at the 0-folder, this has absolutely nothing to do with icoFoam or pisoFoam. The solver haven't touched your files yet. |

The transition layer is probably only there because you chose to view point-interpolated field values in paraview.
