helical conical spring simulation, equilibrium not achieved

Hello everyone,

 

I'm trying to simulate a helical conical spring  to acquire spring k-value.

 

Beside the spring itself, I modeled a circular disk on each side of the spring to support and to apply force.

 

I use large displacement and soft spring to solve it.

 

Everytime I execute, the dialogue pop out, tell me that equilibrium not achieved.

 

I checked previous post and checked my contact condition, can't figure out what's going on.

 

The spring itself will contact after force applying onto, so I set no penetration between sweep body; and both the disks on each side are set BONDED to the spring.

 

Is there anything I miss-operated or I forgot?

 

Please check the attachment and give me some advices.
