Hi All,
I'm a beginner in CFD/OpenFoam. I'm trying to make a simulation with pimpleFoam. I would like to use kOmegaSST as turbulence model. I used the pimpleFoam pitzDaily tutorial material as example. I think I changed all the parameters in order to use the KomegaSST turbulence model but an error I can't understand remains. The error is about omegaFinal. The error message in log.pimpleFoam Code:
DeltaT = 0.000111111 Time = 0.000111111 smoothSolver: Solving for Ux, Initial residual = 0.961556, Final residual = 0.00587764, No Iterations 1000 smoothSolver: Solving for Uy, Initial residual = 0.999952, Final residual = 0.00642699, No Iterations 1000 smoothSolver: Solving for Uz, Initial residual = 0.94829, Final residual = 0.00264515, No Iterations 1000 GAMG: Solving for p, Initial residual = 0.866831, Final residual = 0.00840605, No Iterations 3 time step continuity errors : sum local = 1.48906e-05, global = -1.45615e-06, cumulative = -1.45615e-06 GAMG: Solving for p, Initial residual = 0.0490086, Final residual = 9.64383e-08, No Iterations 14 time step continuity errors : sum local = 2.82694e-09, global = 3.34429e-10, cumulative = -1.45581e-06 [0] [6] [6] [6] --> FOAM FATAL IO ERROR: [6] keyword omegaFinal is undefined in dictionary "IOstream.solvers" [6] [6] file: IOstream.solvers from line 0 to line 0.
