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 in file /home/ishan/OpenFOAM/OpenFOAM-1.7.0/src/thermophysicalModels/specie/lnInclude/specieThermoI.H at line 67. FOAM aborting ............................................. Regards, Ishan |
