Following loads in structural

Hi,

I am loading a part in structural (non linear with large deflections) and the displacement load is not a following load.
Ill try to explain - I am inserting a displacement in the global Zdirection, but since the displacement is large, the load in real life doesnt stay in the Z direction for the whole analysis period, it should change its direction based on the new geometry every step.
Is it possible to make the displacement load follow the geometry?

Hope I explained myself good enough...

Thanks.

Hi!

Search the documentation for the FOLLW201 element type.

Hope this helps

Hi!

I would like to add a question to this thread if I may. In my model (static structural) I want to apply both a remote force and a rotation about an axis. I am working with four bodies that are stacked on top of each other. At each body I need to apply a force in its center of gravity and I need the force vector to always point the next body's CoG. Due to the rotational movement which is only applied on the upper body I would like to use a follw201 element. I read the documentation, but am not able to implement the necessary apdl command (I am working in workbench). I am new to ansys and would really appreciate if your could help me out.

Thanks a lot
