Modeling 3D external Flow over a streamlined body.
 
Hi, I'm attempting to run a 3D flow simulation over a streamlined human powered vehicle body. The body itself is an imported para-solid shape from SolidWorks. I have already completed a surface mesh of the body in a 3D flow environment and set the physics conditions.

I created the geometry, vector and scalar scenes but I can't view the flow around the faired body. Is there something that I am doing wrong?

Here is an image of the fairing in the 3D flow environment:

Here's another one:

You have already meshed the surface, ok. But do you also have an volume mesh? Without an volume mesh you will not be able to compute the solution and that results in no results.

Yes I have a volume mesh as well. I guess my problem is setting the physics in the correct way and setting my force coefficient monitor properly, which is currently giving me values of 0.

Would you happen to know how to set these up for 3D flow?

Please give details regarding how you're setting up your parameters.

Are you sure you have volume mesh? Can you show some plane sections of you model meshed?
