You do laminar when the flow is laminar and turbulent when the flow is turbulent.
You use steady when the flow is steady and transient when the flow is transient. |
Quote:
If you run a transient solver and your solution has a physical steady state, you will reach it after the time derivatives vanish. Conversely, running a steady state solver in a flow problem that does not admit a physical steady state will drive you to get oscillations in the residuals. In any case, you need to know the physics of your problem if you want to do a correct CFD analysis. A CFD code is only a stupid numerical algnorithm, it says nothing if you are not able to understand what you are doing |
