Trouble Converging in Ansys 14.0 workbench (Assembly)

[ju3dan]

Hi everybody, I've been reading this site for some time and always has proven to be useful.

But now I don't really now what else to do. I have a little experience in Ansys and only in workbench.

I have an assembly, about 20 parts. I'm having trouble with convergence. It actually does give me back results of deformation
and stress but it says is unconverged.
I'll make a list of the things I've done so far, so if anyone has some suggestions that may help it would
be really helpful.

-Connections checked, as far as contact tool and Initial information looks good (only one orange warning)
-No weird deformations or strange movements,so I'm guessing contacts should be fine.

I have checked the force convergence diagram of the solution information and my purple line is never crossing the blue one.
This is my actual concern now,knowing the meaning of this diagram and how to make it converge.
Is it because the loads are too big?, or too sudden?
-I've made tabular forces with steps so it's more progressive.
-The newton-raphson residual forces aren't giving me any clues either, the forces are pretty low

If there's any information that may give you more clues about what might be the problem, I'll try to post them.

Thanks in advance!

I also forgot to mention
-I've got activated weak springs with Facto 10
-Large deflections ON
-and the substeps are
Initial Subs 03
Min subs 05
Max subs 15

in case it helps
Thanks again
