Plese suggest me how to calculate drag coefficient of bluff body.

Hi,

1. <LI>Do accurate simulation.</LI> <LI>Use CFX-Post to get drag force on the body.</LI> <LI>Calculate drag coefficient using standard drag coefficient formula.</LI>

for calculation i need pressure at points... how to draw polyline on body and CEL for a problem kindly give me proper guidence as i am new to this topic.

Hi,

You can either set up monitor points which allow you to track the pressure as the simulation progresses or you can extract the pressures as post-processing in CFX-Post.
