Hi everybody,

I have recently immigrated from Fluent to OpenFOAM, so maybe this question looks weird
I'm solving classic flow of Taylor-Couette (the flow in narrow gap of two rotating concentric cylinders). The results of simulation in Fluent are exactly what I was expecting, but OpenFOAM gives strange results, as you can see in the attached photos. The vectors are slices of the 3D domain, the inner cylinder is rotating with 0.6 rad/sec and the outer one is fixed. As it's apparent from the photos there's a linear velocity for the outer cylinder which is certainly wrong. there's no inlet/outlet BC, the BC for the inner cylinder is rotatingWallVelocity and the BC for the top and bottom faces is symmetry.

Any idea is appreciated
