rhoCentralFoam
 

I want to know "rhoCentralFoam" is a steady solver or a transient solver ? Thank you

As you can see in controlDict of any rhoCentralFoam, there is startTime and endTime, so it is transient.
Also in the description it is written this is a density based solver, so it has to be transient

Hello Mahdi,

I do not understand density-based solvers well. Could you please explain why a density-based solver must be transient? I have read elsewhere that density-based solvers are also coupled (as opposed to segregated in pressure-based equations), but I cannot see anything in the source code that identifies, say, sonicFoam vs rhoCentralFoam, as density- or pressure-based.

Thanks,

Daniel

OK， Thank you very much. I get it.
