hi everyone
i have a question. i solve a model in steady state mode. it solved velocities and turbulence. now i want to solve it in transient mode and solve just a transport equation and not solve momentum and turbulence equations. (cuz of time) can anybody tell me how to freeze solving momentum and turbulence models?i need these variables be fixed and cfx just solve a transport equation thanks |

Hi Ludwig, I am big fan of your work.
Under expert parameters there is a tab called "Model Overrides". Set solve fluids and solve turbulence to f (false). |

Be careful when freezing equations, you can only do that if the solution of the new equation has no influence on the properties, or other quantities required to solve the frozen equations.

I am quite happy that Prandtl himself joined this forum. All our problems will be solved in no time now
