[Nek5000-users] mixed Velocity BC's

[nek5000-users at lists.mcs.anl.gov]

Ultimately I'd like to be able to do this on any general surface.  Basically, impose a slip velocity in the streamwise direction with a specified gradient (so w_y=0 and u_y=const in a y-plane), no penetration in the wall-normal (v=0).

Thanks,
Andrew
