Hello,
how can I load a generic flexible beam with a distribuited load on Simscape Multibody (instead of the traditional lumped force applied at the ends of the beam)?
Fig. 1: Example of beam with uniform distribuited load q.

It is strange that Simulink does not allows to load beams with generic force distribution along the length of the beam...
Thanks and best regards, A

Hi Alberto,
Thanks a lot for your suggestions. Actually, the deformation is what I'm interested in. I initially did apply the forces like Juan suggested, but I was hoping for a more generic solution.
Thanks again and I hope your problem is resolved now.
Best regards.

Hi Alberto
This can be done by adding the discrete nodes with help of rigid transforms.
Unfortunately, the nodes will not follow the profile of the beam exactly. But it can be a reasonable approximation.
Hope that we can expose the nodes in future releases.

At the moment I am not working on it so I cannot check, but I am quite sure that it can work. I will accept your answer.
Thank you,
Alberto.
