Help with my FEA simulation?

Hello,

I'm trying to perform a FEA simulation on a telescopic fork. Im trying to find the displacement due to the bending moment when the fork is fully extended. I applied a load of 5000 N and fixed the geometry from bellow. However I am getting this error every time I solve:

"The Iterative Solver stopped.

The solver has numerical difficulties.

Model may not have adequate fixtures

No results saved."

I read on this form that I'm suppose to add fixtures such as springs, but I have no idea where to apply it.

Any help would be appreciated.
