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.
