hello i'm trying to plot forces. i ran a VWAT wind turbines with three airfoils but the forces of the three airfoils are not having the same amplitude .could you please help me

Hello, and thank you for your response. I am currently using PimpleFoam for my simulation. I am trying to plot the forces (both in the x and y directions) acting on each airfoil of a vertical wind turbine. Unfortunately, I have noticed that the forces on each of the three airfoils do not have the same amplitude. I would appreciate your assistance in resolving this issue.

What do you mean by "the forces on each of the three airfoils do not have the same amplitude"?

What do you expect to have?
Are you comparing with experimental results?
How are you computing the forces?
