motorbike BCs: Slip vs. zeroGradient
Hello all,
I am using the OF1.6 motorbike tutorial as a template for kOmegaSST turbulence model in OF1.5-dev.

So I have seen on the forums that people use zeroGradient for external flow BCs on the faces other than the "inlet" and "outlet". What is the difference here in using slip instead of zeroGradient? Is it because of the turbulence model?

Also, the motorbike file structure shown here:

In the omega file 'object' is set to 'epsilon'. Is this a typo?

Thanks to all.
