I think the interpolation sheme is the problem. I changed in the sampledict the interpolationScheme to cell (constant over cells) and the type to midPoint (one Point per cell) and the results are...

Hallo,

here are the velocity-profils made by the sampledict with the three interpolation schemes: cell, cellPoint and cellPointFace.

The set was made by a uniform line with 40 values from r...

Axissymmetric pipe Simulation with unequal zero wall velocity

Hallo all,

I built an axissymmetric mesh with the blockmesh utility. It is a pipe with an inlet and outlet, on top a wall, down is the axis and left and right are wedges.
The radius is about one...
