Fluent VS CFX

mahdi57 · September 28, 2010, 13:14

Could anybody let me know about the exact differences between CFX and Fluent? I know that Fluent is based on Finite Volume. The CFX is also based on Finite Volume OR Finite Volume?
Finally, I want to know which one is better to use?

I think your question is too general. There are lots of differences and lots of similarities. The best one to use is the one that works best for your application. In many cases either would be suitable.

Dear Stumpy,

Thank you for your reply. Please let me know:

1- CFX is based on finite volume OR finite element?
2- I wanna use one of them for modelling of flue gas in boiler. Which of them is better for this application (viscouse subsonic fluid flow with radiation and convention heat transfer + turolency)

CFX is finite volume, but is uses many concepts from finite elements such as shape factors and integration points.

Both CFX and fluent should be able to model your flue. Try them both out and find out which works better for you. General comments about one being better than the other are rarely accurate.
