Dear forummembers,

I am running a 2D multi-element airfoil simulation using an o-grid. The solver used is simpleFoam and I use the kOmegaSST turbulence model.
I first tried to to this simulation in a square domain, which worked fine. However, since I need do a sweep of angles of attack I switched to a circular domain. I use the inletOutlet boundary condition. Yet, with the new domain I keep getting a printStack error. Searching the forum I did find something. But I am not sure what to do with this information. It says that the problem of the topic starter might be in grad(U_). Does this imply my U should not be a uniform field, because then grad(U_) will be zero? Or should I be looking elsewhere?

Thanks for reading and I hope some one can help.

Nick
