CFX - Flow Over a Moving Body (Lift & Drag)

rossbardon · January 5, 2010, 15:48

Hi,

I am a beginner with CFX. I am having to use it as part of my masters course. We have been set the challenge of modelling 3 very basic automotive bodies and then carrying out flow simulations over the bodies. I have completed the obvious tutorials, they have helped me set up and run test rests without any problems! The tutorials have not helped significantly with the result I require such as:

Lift Force
Drag Force

I would like some advice, or direction on good tutorials, website to view to help me with this.

Thanks in advance to any contributors!

you can get the force x,y,z component on a surface (or a user defined group of surface) in cfd post

you will probably find handy the search function in this forum and a good fluid dynamics book
