According to your drawing, your lift is on z-axis and your drag is on x-axis. I don't know the name on the force coefficient on the third direction that you have drawn. When you select Lift...

It should be the same distance as your radius for the far field. In aerodynamics, it could be hundred times the dimension of the plane. You need a cluster for such...

As Syavash said, your domain must be enough big to apply the symmetry condition which means that there is no no mass transfer on that surfaces....

You must run calculation to have the flow field velocity because the lift coefficient is related to you flow field velocity and pressure. I don't know why it's drawing something when you click on...

Stationary is for the boundaries that are not moving like your far-field and the two symmetrical boundaries Deforming is for a deforming boundary or zone such as your fluid Rigid...

Did you select "Remesh" when you have selected "Dynamic Mesh" ? Use "Previewing the Dynamic Mesh" button, so that you see what is going on before running your simulation. The "Minimum Orthogonal...

Maybe you need very small elements in the zone where you have your movement (trailing edge) at the beginning of the simulation. The dynamic mesh destroys the...

Maybe you're talking about the projection of the Lift. The Drag (Fx) and Lift (Fy) which are orthogonal never change direction. The lift is always on the same direction as the gravity (vertical) and...

If you want to automate it, you can use parameters to change the angle but I wouldn't recommend that. The process would be: 1. Create a new project 2. Choose an...
