PZT manufacturers often put electromechanical coupling coefficient (k) in their data sheets. This coefficient shows how much electrical energy converted into mechanical energy, and vice versa.
In COMSOL 5.0, what is the correct way to take into account of this coefficient?

How to include electromechanical coupling coefficient in piezoelectric COMSOL simulation? First I suspected it would be the "Coupling Loss" in the "Piezoelectric Material" node. But doesn't seem correct.
