Reading data from local coordinate frame
 

Hello!

I am running in CFX a wind turbine. For those who know, it's NREL.

I need to have the pressure coefficient over the blade's profile on 5 different sections. To do so, I've created a polyline in CFD-Post for each section (see image). As I need the data as a funcion of the local chord length, which changes direction as a function of the distance to the center of the rotor, I created also a local coordinate frame for each section (see image).

I've created the local coordinate frames in CFX-Pre before the run and in CFD-Post after the run too. However, I am struggling to discover how to select these local coordinate frames to have the data plotted as I want.

If anyone can help me, I'd be really grateful.

Yours sincerely,
Marco
