The Piezoelectric Waves, Time Explicit multiphysics interface (
), found under the
Acoustics>Elastic Waves branch (
) when adding a physics interface. This interface combines
The Elastic Waves, Time Explicit Interface and
The Electrostatics Interface together with a dedicated multiphysics coupling and material models. These add the constitutive relationships required to model piezoelectric phenomena in the time domain for wave propagation. Both the direct and inverse piezoelectric effects can be modeled and the piezoelectric coupling can be formulated using the strain-charge or stress-charge forms.
When adding the Piezoelectric Waves, Time Explicit multiphysics interface a dedicated time explicit version of the Piezoelectric Effect multiphysics coupling, called
Piezoelectricity, Time Explicit, is added. The feature is used to couple the
Piezoelectric Material node in Elastic Waves, Time Explicit to the Charge Conservation, Piezoelectric node in Electrostatics.
