Small amounts of vorticity show up on the processor boundaries when using linearUpwindV scheme for convection terms on a test case. See this thread for detailed description. http://www.cfd-online.com/Forums/openfoam-bugs/94085-strange-processor-boundary-behavior-linearupwindv.html#post330781
---- additional_information ----
Other schemes do not show this behavior (tried QUICKV, blended, limitedLinearV, linearUpwind). SFCDV shows behavior slightly but dissipates after initialization.

I'm assuming this is a bug.
