Hi,
I've installed OpenFOAM-2.0.1 few days back and started using it. In all the tutorials for rhoCentralFoam, I see mu =0 in thermophysical properties. If I want to change it's value for laminar case, it returns error like this ---------------------------------------------------------------------------------------- --> FOAM FATAL IO ERROR: keyword e is undefined in dictionary "/home/rajesh/OpenFOAM/rajesh-2.0.1/run/tutorials/compressible/rhoCentralFoam/forwardStep/system/fvSolution::solvers" file: /home/rajesh/OpenFOAM/rajesh-2.0.1/run/tutorials/compressible/rhoCentralFoam/forwardStep/system/fvSolution::solvers from line 22 to line 38. From function dictionary::subDict(const word& keyword) const in file db/dictionary/dictionary.C at line 461. FOAM exiting --------------------------------------------------------------------------------------- I don't understand how to proceed, can somebody help? Also in programmers guide I see mention of a tutorial with non-zero mu for forward step case (sonicFoam case), but I don't see the same in the installed folder. Also, could somebody give some reference where laminar/turbulent cases at high reynolds no. have been solved using rhoCentralFoam. |

You should specify solver for e in fvSolution.
For example, instead of Code:
U { solver smoothSolver; smoother GaussSeidel; nSweeps 2; tolerance 1e-09; relTol 0.01; } Code:
"(U|e)" { solver smoothSolver; smoother GaussSeidel; nSweeps 2; tolerance 1e-09; relTol 0.01; } |

Error in Prandtl number

I've just found that Prandtl number in rhoCentralFoam is always 1 (independent of what you have set in constant/thermophysicalProperties).
See bug http://www.openfoam.org/mantisbt/view.php?id=475 |
