Hi everyone,

Actually, I'm working on the aerodynamics of 3D models such as road cars. So I need to plot the evolution of drag and lift forces over the longitudinal direction of the car for example.

To do that, I use CDF-Post to create 100mm wide Iso Clips, and calculate aerodynamic forces on them. But that solution is too long in time. So I'm looking for another faster solution through FLUENT to get those data. Do you have some ideas ?

I was first looking for use XY plots, but they're not available. So I don't know where can I search on the soft, and I' have not find a solution on the internet. This problem looks basic, so sorry if there are already topics about that. I'm beginning with FLUENT, maybe I did not use good keywords.

Thanks a lot,

Avalou

Sorry, I've made a mistake about XY plots. They are therefore well available, but the solution doesn't seem to be there. Moreover I've seen there are solutions using monitors, but I don't understand how I could follow the evolution of drag along the longitudinal axis of the car for example. For me it gives a single value for the global drag (at each iteration of course) but not several values along an axis for computing a graph then.

Hope I'm pretty clear with my explanations...
