What is the best way of modelling multiple flexible bodies in simulink/simscape, such that the simulation runs smoothly?

The photo above is a snippet of my current simulink model. It is showing a flexible rectangular beam attached to wheels (bottom wheels are fixed and middle/top wheels are dynamic). this set-up runs with no problems.

In this set-up the wheels are connected to the body via rigid transforms from the bottom edge of the plate, this means that as the plate bends during contact, it will bend with respect to the bottom edge, and not at the location of the middle and top wheels, so its slightly innacurate.

However, when i try to split the rectangular beam such that it is now 3 flexible bodies connected to each other, split at the location of the wheels (top, middle, and bottom), the simulation will run but nothing will happen, it seems to struggle with simulating multiple flexible bodies connected to each other?

Im not sure if this is a solver issue, or a modelling issue?

any help would be greatly appreciated.

Hi @sherif,

Can you share the model file.
