cfd^2 Member cfd^2 Join Date: Mar 2013 Posts: 31 Rep Power: 13	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?

ghost82 Senior Member Rick Join Date: Oct 2010 Posts: 1,016 Rep Power: 26	From fluent user guide: Note that for axisymmetric problems, this mass flow rate is the flow rate through the entire ( -radian) domain, not through a 1-radian slice. Also velocity (obviously) is the same. Daniele jamalf64 and cfd^2 like this.
