Paul,

Great!  Katie mentioned a solution to the "ERROR" message -- I think the only remaining thing is the representation of the azimuthal velocity.

This approach required one to add appropriate terms into the .usr file.  Is this still the case, or is Nek's third velocity component now the azimuthal velocity?
