Hello,

So I am currently doing a project for a class, and it involves modeling different bumpers to see how they affect the air flowing through an engine oil cooler on a porche 914. I have just started using Flow Simulation, and am having trouble choosing the right goals to find the air flow through the cooler. To describe my problem set up:

Testing Initial Conditions of 40 70 and 110 mph

External flow through Air at 293 K

Current Goals are Total Pressure and X component of normal force (drag)

Pictures of assembly are attached.

I am assuming it is a surface goal, but I am not sure if I have to create a surface, like a lid used for the internal flow tutorials, that would not affect the air flowing through the cooler.

Any help would be appreciated!

Justin
