Hi,
Instead of rubber bellows I have used Cbush element and given stiffness to it. I want to give preload also. I have checked we cannot give preload to cbush element. CROD,CBAR,CBEAM support for giving preload. Is there any option (spring type) to give preload and stiffness to 1D element simultaneously ? Please let me know soon.
Regards,
Pratik
