loaded flexible beam as initial position Simscape

Hello,

I would like to model this system (picture) at the steady state. This is a kind of double pendulum, which is resting of 4 small flexible beams (atcing like springs).

My problem is that it defines the beam with no charge on it so when I start the simulation, it oscilates a lot and it takes too much calculus to reach the steady state.

Is that possible to start the simulation with loaded beams?

I can calculate the deformation of the beam when it is loaded and I would like to put this deformation as a parameter somewhere.

Thank you,

Hello Vermeer,

I also meet this problem,but it isn't solved.Have you solved this problem yet? Could you please share some experience about this question?

This is a great model - thanks for showing the animation.

You cannot specify the initial deflection for the beam through R2022b. You can save the final state of a Simulink simulation where everything has reached steady state and then start the simulation from there. You can find this on the Simulink Configuration panel on the "Data Import/Export" pane.
