This chapter describes the physics interfaces found under the
Aeroacoustics branch

.
The aeroacoustic branch has physics interfaces to solve the fully linearized acoustic equation for several physical conditions, they are: the linearized Euler (LE) equations, the
linearized Navier–Stokes (LNS) equations, and the
linearized potential flow (LPF)
equations. These equations are also referred to as
convected acoustics. Flow-induced noise functionality using the Lighthill analogy exists in pressure acoustics when using the
Aeroacoustic Flow Source feature, associated multiphysics coupling, and dedicated study.
