CFD Online Discussion Forums - NACA0012 compressible static simulation

Hi everybody,
I am a new user of openFoam, and I would like to use it to do some dynamic stall simulations for a naca 0012 for M=0.7-0.85.

I think that a good solver for this purpose is rhoPisoFoam with a kOmegaSST turbolence model with a later implementation of the rotation of the grid.
So I was trying to launch a first static simulation at M=0.5 with rhoPisoFoam and the kOmegaSST model at zero angle of attack to validate the solver with some experimental data.

Unfortunatly If I set case with the kOmegaSST model using these conditions
http://turbmodels.larc.nasa.gov/sst.html
I get this error, that lets me think that there is a problem with my thermoPhysicalProperties or the schemes I am using to evaluate them.
I post the case without the grid (that is not my property).

the length of a cell in the flow direction is approximately 0.0045 and in y direction near the wall is 0.0000055. As you can notice the grid is very fine.
Other info about the grid are:

startFace 386060;
}

nFaces 970;
startFace 772120;
}
)

The error I get is this one:

I really hope someone can help me,
thank you very much for any suggestions.
