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.
