Hello, everyone. I am a new OpenFoam user. For training, I use OpenFoam to simulate a 2D Nasa0012 airfoil model. The inlet air speed is 170 m/s. According to User Guide and the on-line documents, I decided to use rhoSimpleFoam with SpalartAllmars model. and the flowfield is assumed to be compressible. I got the following error message at the first iteration.

smoothSolver: Solving for Ux, Initial residual = 1, Final residual = 1.44986e+60, No Iterations 100
smoothSolver: Solving for Uy, Initial residual = 1, Final residual = 3.05799e+54, No Iterations 100

I am not sure if it is just caused by mesh quality, or other issues. And there is rare information I could found for this error message.

I am not sure my setup is correct because I could not find a example for the rhoSimpleFoam with SpalartAllmaras model. Therefore I attached the files for your reference.

Thanks in advance.
