I am simulating a piezoelectric energy harvester. Can someone help me , how can I introduce the air damping in the structure? Thanx in advance

You would need to use the Laminar Flow physics.

Depending on the exact physical properties of the damping, and your geometry, there are also other possiblilties.

If the air damping comes from a thin air layer, the Thin-Film Flow interface may be an option.

Also, using acoustics rather than full fluid mechanics may be an option.
