Pitching-heaving motion
 

I'm new to CFX and trying to model a pitching heaving wing.

I understand I need to specify the mesh motion in the CEL file but can't find any resources to help me how to define this. For heaving in z direction:

meshdisp z = amp*sin(omega*t)

Will the built in variable theta work for pitching as long as the coordinate system lines up with my pitching axis?

thanks
