Blasius - flat plate

First, excuse me for my english...

I'm trying to simulate Blasius flat plate boundary layer (on FLUENT) but I have some problems with the Boundary Conditions...

I don't know what to do with the upper BC.

I would like to do a slip condition for the x-velocity without imposing the y-velocity. Is that possible? Can i set a dw/dy =0 (no variation of the y-velocity) BC pour the y-velocity?

Any ideas for this problem?

My problem is that the y-velocity approach a constant value that is unkown before the simulation. But for the Blasius case, i need that the x-velocity stay constant all the upper BC.

Thank you for your help
