How Does Fluent Handle Volume Flow in 2D and 3D -- CFD Online Discussion Forums

July 15, 2008, 16:20	How Does Fluent Handle Volume Flow in 2D and 3D	#1
Shawn Guest Posts: n/a	I am running a model in both 2D and 3D with the same X & Y dimensions. After iterations based on a constant pressure or velocity inlet boundary conditions, I observed that the resulting velocity vector plots are similar but the volumetric flow rates at the inlets and outlets are dramatically different. This totally makes sense. But I'm curious as to how exactly FLUENT treats the 2D model. I can't seem to find that information anywhere. Also, can I obtain any scaling factor to convert the 2D flow data into 3D flow data (for faster simulations)? Thanks!
