Modelling Dampers

How can I model a viscose damper as an element between two nodes with no stiffness?

use a truss element with the viscous material.

thanks for your help , but i want to know if we can make the stiffness zero?because i want to have pure damper.

the stiffness in that truss will be 0 if you use the ViscusMaterial .. browse the source code
to see for yourself

could you use a zero-length element with the viscous material if the length of your damper is negligible?

Thanks for your help , that must be a good idea.
