Drag Coefficient Help


#1

Hello, I’m a Newbie and I am trying to figure out how to use the Forces and Moments (coefficients) tool.

When I first used it I got absurdly large numbers in the post-processor. I believe it may be because of this:

For context, I’m trying to find the drag coefficient of a Greenpower F24+ car. My problem is that I do not know how I am supposed to fill out these sections shown in the screenshot.

In my model the airflow is in the Y-direction, so I put the drag direction as Y and 1 m. But I do not know what this distance relates to. Is it supposed to be length of the car?

Thank you very much for any help!
