Radial load in Millipede Topostruct2D & Topostruct3D

Hello everyone !,

Is there a possibility or a way to set loads as "radial" in Millipede ?
The "radial" option is available in the Sawapan Topostruct software, at least for the 2D system (see screenshot).
Actually, I would like to apply torque loads to my models both in 2D and 3D. I know it is quite different and difficult to manage in 3D, but I am wondering if it's possible and how to built the model.
Can we manage to manipulate the axis of "rotation" ? How can we perhaps apply conditions to the loads ? I thought about setting a vector field But I do not know how to build it and connect it to the load.

Thank you very much for your help ! I hope this might help everybody.
