So my goal is to measure the drag coefficient of different models. This was my take on a sphere. As I googled I found out that the cd value of a sphere is normally around 0.48. However if I try to simulate in simscale I get a value of 620. What do I do wrong?
Hi!
I would need to review your setup and see if it has an error, for example in the reference are, reference length, mesh fineness, etc.
If you would like to check for yourself and learn, we have a few articles on this topic:
