Hi,

I am a new user and I want to simulate a supersonic flow inside a scramjet engine. I wanted to know that how can I input viscosity model in sonicFoam according to Sutherland's Law?

And while I was running sonicFoam normally I got the following error. Please help.

.................................................. ............
Time = 1e-06

Courant Number mean: 0.365693 max: 513.429
diagonal: Solving for rho, Initial residual = 0, Final residual = 0, No Iterations 0
DILUPBiCG: Solving for Ux, Initial residual = 0.433151, Final residual = 4.94217e-06, No Iterations 11
DILUPBiCG: Solving for Uy, Initial residual = 0.443171, Final residual = 3.61082e-06, No Iterations 11
DILUPBiCG: Solving for e, Initial residual = 0.799934, Final residual = 2.7764e-06, No Iterations 19


--> FOAM FATAL ERROR:
Maximum number of iterations exceeded

From function specieThermo<thermo>::T(scalar f, scalar T0, scalar (specieThermo<thermo>::*F)(const scalar) const, scalar (specieThermo<thermo>::*dFdT)(const scalar) const) const
