Hi I am trying to validate Solidworks Flow simulation using this tutorial http://www.webpages.uidaho.edu/mindworks/Adv%20Solidworks/CFD/Drag%20coefficient%20of%20sphere%20-%20Final.pdf I seem to get reasonable values for Cd for Re 10 but for Re 10,000 the Cd value seems quite off 0.17 (solidworks)  instead of about 0.4 (theory). Any help with trouble shooting this to get the correct value would be much appreciated. I have attached the model I did in the post.
