Fan curve table
 

Hello,

I am doing aeroacoustic simulation on a fan in a cylinder domain.
I use "in-place" interfaces and "fan interfaces" as type in the properties windows.

In physics conditions, I setted fan curve as "Table" and then I need to input the table in the physic values.

The problem is I don't know how could I get this table ??

If someone knows something about this, please I would appreciate some help.

Thank you.

Typically when someone elects to use the fan interface or the fan source you are trying to approximate the behavior of a fan with known performance. Either that or you have some idea of the delta P and swirl characteristics you want to duplicate.

Are you trying to examine the aeroacoustic properties of the fan itself? If so, the interface/source approach is wholly inappropriate. You should be modeling the fan and using rigid body motion and modeling the blades of the fan rather than approximating their effect.

Thank you, I understood that I must used the rigid body motion for the unsteady simulation because I am trying to examine the aeroacoustic properties of the fan itself. But when I did it, a warming windows appears saying: "a floating point exception has occurred: floating point exception [Overflow] Context: star.segregatedflow.SegregatedFlowSolver"
maybe it comes from my under relaxation factor values for velocity and pressure, I really do not know ... by the way thank you for your quick answer :)

Try using a coupled solver if the segregated approach is failing. Its a better method for this anyway.
