Squeeze filme damping in FSI

Please login with a confirmed email address before reporting spam

Hello everyone,

I was wondering if the Fluid-Structure Interacxtion module would be suitable to simulate the squeeze film damping effect?

To be more precise: Im simulating a vibrating cantilever in air environment and considering I am in the micrometer scale I need to take into account the damping due to squeeze film, my idea was to use the FSI module to calculate the damping ratio and use it as a raw parameter in the damping of a normal Solid Mechanics simulation. Does anyone know if FSI take into account squeeze film effect?

Another way I tried is the thin-film damping but I can´t make it work, any suggestion?

Thank and all the bests,

Edoardo.
