Strange problem

[andrea_pontiggia]

I do not understand these results ...

Robot 2014 calculates the model, but it returns the following results.

Do you have any idea?

Thanks

It usually means that the obtained values are extremely large. Any ignored instability or divergent nonlinear analysis?

You're right!

I mistakenly left out of the instability of some nodes ...

Now it all works.

Thank you very much
