Dear Foamers!

I am currently trying to simulate a flow around a RAE2822 airfoil. Here are the inlet conditions: Re=500 then Re= 6,500,000 Mach=0.5, AoA=2.92.

I want to use rhoSimpleFoam solver to do so. First, I wanted to simulate the turbulent flow and then I decided to go back to laminar flow.

My domain is composed of : upstream and downstream, limitbox, intrados, extrados and symmetry.

I am using the following boundary conditions (please find them in attachments).

The simulation starts but fails within three steps. The error is the following:

Foam::GAMGSolver::scalingFactor(Foam::Field<double >&, Foam::Field<double> const&, Foam::Field<double> const&, Foam::Field<double> const&) const in "/home/EUCLIDE/truong_nm/OpenFOAM/OpenFOAM-1.6/lib/linux64GccDPOpt/libOpenFOAM.so"
#4 Foam::GAMGSolver::scalingFactor(Foam::Field<double >&, Foam::lduMatrix const&, Foam::Field<double>&, Foam::FieldField<Foam::Field, double> const&, Foam::UPtrList<Foam::lduInterfaceField const> const&, Foam::Field<double> const&, unsigned char) const in "/home/EUCLIDE/truong_nm/OpenFOAM/OpenFOAM-1.6/lib/linux64GccDPOpt/libOpenFOAM.so"
#5 Foam::GAMGSolver::Vcycle(Foam::PtrList<Foam::lduMa trix::smoother> const&, Foam::Field<double>&, Foam::Field<double> const&, Foam::Field<double>&, Foam::Field<double>&, Foam::Field<double>&, Foam::PtrList<Foam::Field<double> >&, Foam::PtrList<Foam::Field<double> >&, unsigned char) const in "/home/EUCLIDE/truong_nm/OpenFOAM/OpenFOAM-1.6/lib/linux64GccDPOpt/libOpenFOAM.so"
#6 Foam::GAMGSolver::solve(Foam::Field<double>&, Foam::Field<double> const&, unsigned char) const in "/home/EUCLIDE/truong_nm/OpenFOAM/OpenFOAM-1.6/lib/linux64GccDPOpt/libOpenFOAM.so"


Thus, it seems to be due to my schemes parameters. I also attach them.
I searched the forum for similar cases, I tried parameters according what I found but still unsucessfully. Can someone help me to set this case up ?

The mesh comes from Fluent. I converted it using fluent3DMeshToFoam and then scale it to get Re = 500.

Thanks for your help and your answers,

it shouldnot analyzed as a laminar flow case,
i suggest to use sst, or spalart almaras
