Hi everyone,
I am simulating injectormodel using cavitatingFoam. I am using k-wsst model. When i execute the cavitatinFoam command it is running with some foamwarning.Could you please tell me weather the simulation running is corrct one. I got the following foamwarning.At first it has selected the turbulence model but afterwards it is saying Neither LES nor RANS found. Assuming no turbulence. Reading field p Creating compressibilityModel Selecting compressibility model linear Reading field U Reading/calculating face flux field phiv Reading/calculating face flux field phi Reading transportProperties Selecting incompressible transport model Newtonian Selecting incompressible transport model Newtonian Selecting turbulence model type RASModel Selecting RAS turbulence model kOmegaSST kOmegaSSTCoeffs { alphaK1 0.85034; alphaK2 1; alphaOmega1 0.5; alphaOmega2 0.85616; gamma1 0.5532; gamma2 0.4403; beta1 0.075; beta2 0.0828; betaStar 0.09; a1 0.31; c1 10; } Courant Number mean: 0 max: 0 phiv Courant Number mean: 0 max: 0 acoustic max: 30.6928 Starting time loop phiv Courant Number mean: 0 max: 0 acoustic max: 30.6928 deltaT = 1.19998e-08 --> FOAM Warning : From function SolverInfo::SolverInfo(const dictionary& dict,const objectRegistry &obr) in file SolverInfo/SolverInfo.C at line 88 Neither LES nor RANS found.
