Plotting of lift coefficient vs angle of attack??

August 18, 2003, 09:49

Hi.

I'm a new user of Fluent 6.

Currently,I'm doing a project. I need to plot drag coefficient, pressure coefficient and lift coefficient against angle of attack. I couldn't find the variables in the XY-Plot. May I know how to set up boundary conditions for changing angle of attack.

Thanks

Hello, Drag coefficient and lift coeffcient are not available for post-treatment. You need to set a UDF reprogramming both drag and lift model and save both brag and lift coeffcient in UDMI functions. These UDMI function will availeble as post-tretament variable.

good luck, thomas
