2D axisymmetric
 
Hi,

I have known values for mass flow/velocity inlet based on a 3D model. I want to run it in Fluent usinf 2D axisymmetric solver. Do I need to convert the value of the inlet of the 3D case to the 2D axisymmetric one?

From fluent user guide:

Note that for axisymmetric problems, this mass flow rate is the flow rate through the entire (http://www.arc.vt.edu/ansys_help/flu...md0e360431.png -radian) domain, not through a 1-radian slice.
Also velocity (obviously) is the same.
