Nonlinear Coupling of different DOFs

Nonlinear Coupling of different DOFs

Nonlinear Coupling of different DOFs

(OP)
Hello Everyone!
I want to connect two nodes by a structural nonlinear stiffness component. That takes into account "cross-coupling".
(That means non-linear off-diagonal stiffness if you want to see it as a stiffness matrix)
For instance if a Ux occurs I want also a moment response about another axis.
So what I would need is a nonlinear stiffness matrix.
But I have not found it yet. I already know the combin39, but it works just in the main direction.
I could achieve that behavior geometrically. But that could be become very difficult.

So: does anyone know a possibility to obtain that behavior in Ansys?
(Maybe there is a nonlinear stiffness matrix in Ansys. And I only can not find it)
