Hi Nocolas, You might want to try using ChElementBeamEuler::SetDisableCorotate(true) in your test. If the beam structure does not undergo large rotations, the Corotated Euler Bernoulli beam element might (hopefully) simplify to the linear case. However, I cannot be completely certain of this outcome.
If large rotations are present in your system, it won't be possible to simplify to the linear case, as finite rotations are a primary source of geometrical nonlinearity. Good luck!
