Yes there's a cut bc, and I am currently examining it. For the SA model the cut bc value is given that of the opposite cell, which works for previous test cases.

And thanks for that hint, I will...

Yes, the rotor code works for both inviscid computation and B-L model.

I output the rotor flow fields of several time steps before it diverges, as attached.

The density and pressure contour...

Hi,

I was trying to implement the Spalart-Allmaras turbulence model into my FVM rotor solver, which can work well with the Baldwin-Lomax model.

The version of the S-A model I used is the...
