The Thermoviscous Acoustic–Thermal Perturbation Boundary coupling is only applicable for Frequency-Domain Perturbation (possibly combined with a Stationary study) and Time Dependent studies. This is the case as the Heat Transfer in Solids (and Fluids) interface is not formulated in terms of perturbations as all acoustic interfaces are. This typically requires solving for the stationary temperature field in the solid, which then forms the linearization point for the acoustic model. The temperature linearization point can also be taken from the Initial expression. The stationary temperature field can be selected in Model Input for the acoustic model to get consistent material data.
