Hello! I am having issues with my wind tunnel simulation because it gives out negative drag coefficient numbers and am not sure why. Windtunnel If someone has any idea why and how I could fix that it would be helpful. Thanks.
Hi @ngiuliani,
Thanks for posting your question!
I see that your Drag Direction is [0, 1, 0] when it should be [0, -1, 0]. Please try to change it in the Result Control, run your simulation again, and then let me know if this works 
best,
