Hi, I'm making a calculation involving species transport and I tried to first establish the flow field and then turn on the species transport option WITHOUT solving simultaneously the fluid flow equations for each phase (3), but it seems that by doing this the species contours doesn't show turbulent diffusion behavior. Is there a way to include the turbulent diffusion and only solve the species transport equation?

Just for clarification, you have the option to check/uncheck the species equations yes?
You can freeze the flow solution and still get the turbulent species transport term. You can also freeze the flow and turbulence solvers. You just need the species transport solver still selected. |

Thanks for your answer. Yes, I have the option of species transport on, but the contours show the same pattern of the velocity vectors. I'll try to freeze/unfreeze the flow equations to see if it changes.
