'' The properties Longitudinal Damping and Preload are not applicable for Springs with nonlinear stiffness. ''

 Use a COMBIN14 linear spring if you want a spring with damping and preload.

It is not straight forward but possible to do in a manual way.

This video shows how

Hi, thank you for the reply , this seems too complicated for my model I have 700 springs in the whole model

Hi peter ,  I only want pre loading with non linear spring , no damping is it possible in combine 14?

Combin14 is a linear spring element.

Hi peter ,  I tried with COMBIN 14 it dint work like the way I wanted. its a linear spring
