When should the temperature_flow stagger be used?

Recommended Posts

We typically suggest to use temperature_flow if the properties are strongly dependent on temperature. Treating flow and temperature as one large matrix can aid convergence in these cases. The degree to which it aids convergence will be extremely problem dependent, so it is difficult to make a blanket statement. If the free convection is dominant, temp-flow would have more effect than if the forced convection is dominant.


If the flow equations don't depend on temperature, solving them separately will be faster.
