My project need a AnyForce3D being applied in the negative y direction with respect to the node shown in the attached image. However, the force is acting vertically downward (as shown in black color in the attached image)
I appreciate any advice to align the force with negative y direction with respect to the node.
You can do that by specifying the force vector as Flocal instead of F. F inputs the force in the global reference frame, while Flocal inputs the force in the local reference frame.
