Problem in plotting drag coefficient

Sarinagara · September 27, 2010, 07:23

I am a beginner in using Fluent. When I want to plot the drag coefficient after I've calculating the flow over a ball in Fluent, there's an error:"No data to plot." Please tell me why it happened. Thanks a lot

You need to specify what surface you are calculating drag from in the force monitors menu. Also you should monitor drag throughout the calculation to see if the drag coefficient has reached a stable value not just accept the value once the solution is converged.
