Hi, I was wondering how to set up force and moments coefficient. I want to have the coeficents of my forces acting on my aircraft but I dont know how to set it up. When you go into forces and moments coefficients. It has all these numbers. I need some help on finding out what they do and how to correctly enter them.

Here is the project link:

Thank you so much for your time,

Thank you I just need clarification that if you were to select the whole asembely for the faces that the reference area would be the surface area of the whole entire assembly or just half? Or If the reference area is something else please let me know?

Thank you,

Hi again, I don’t know what faces to select for force and moments. do I select anything or leave it blank? if I do select anything do I select the whole thing?

You will have to select the faces of the CAD model :slight_smile:
