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

P.S. I have attached the contents of the 0 folder to this post.

Code:
Pstream initialized with:
    floatTransfer     : 0
    nProcsSimpleSum   : 0
    commsType         : nonBlocking
sigFpe : Enabling floating point exception trapping (FOAM_SIGFPE).
fileModificationChecking : Monitoring run-time modified files using timeStampMaster
allowSystemOperations : Disallowing user-supplied system call operations
