I saw a few videos, on how to set reference values to calculate Lift and Drag coefficients. But I just came to the conclusion, First Ansys calculates the lift and drag force, and using reference values it calculates coefficient, isn't it? Also, can you tell me the dimensions of the 2D external flow domain for the sphere? Is the domain shown in the image is correct (D is the diameter of a sphere)
