    Hi @Ariane Rebelato

     

    You can use CELAS elements with PELAS property in which you can specify damping. 

     

    Please let me know if you need any help with the same.

    You can also use CBUSH element :)/emoticons/default_smile.png' srcset='/emoticons/smile@2x.png 2x' title=':)' width='20' />

    @Ariane Rebelato like mentioned by farouk, using CBUSH with a PBUSH property allows you to use both stiffness and damping as needed.
