How to write UDF for pitching&plunging airfoil?

Alex

Hi,

I am currently trying to write a UDF file for an airfoil in pitch and plunge to perform unsteady 2-D analysis.

I have no experience writing a UDF file, so I was wondering if you could give me a tip on how to integrate the following equations into my UDF. I think I need to use the DEFINE_CG_MOTION UDF.

For my plunging motion:

h=h_0*sin(omega*t)

For Pitching:

theta=theta_0*sin(omega*t+delta)

Your help would be greatly appreciated.

Thank you very much

Alex
