Any known limitation on amount of flexible bodies in a model with multiple fixed connections in between?

Hello,

I would like to know if anyone has already encountered limitations as the complexity of the flexible bodies increase as well as the number of fixed/bushing connections between them.

While working in a non conventional project, we are trying to do a load cascading with multiple complex flexible bodies with more than 10 connection points between some of them. There is not any rigid part in between them.

Is there any general known limitation or rule in order not to fail into wrong loads?

We have experience with these activities before with successfull results, but we are wondering in the increase of connection points could be an issue for the load cascading.

Thanks,

Javier

Hi Javier,

If you have those many fixed joints between two flexible bodies, you need to make sure you have enough number for normal modes requested. In this way, you can make sure that higher order bending and torsion modes can represent the flexibility of the material between these fixed joints.
