think I found the problem

You defined
the spring/dashpots for part in property module, but I defined it in assembly
module because I do not know how you defined it in property module, I need 2
points to make spring/dashpots that I make them by reference point, also I assigned
equation constraint to them. How I could define spring/dashpots without
reference points?

I
checked your model, your points were node [52] and node [53], how you made and
selected them?
