Question Velocity Component

If I want to change wind attack angle on a certain object, is it better to use xyz components of velocity rather than to rotate the domain, changing the geometry ?

Would the components introduce some additional error ?

Thanks !

In theory, it should not affect.
If gravity is involved, then make sure that the gravity vector is also tilted.
