The same considerations for the mesh apply for the Nonlinear Pressure Acoustics, Time Explicit interface as for The Convected Wave Equation, Time Explicit Interface. Details are found in Meshing, Discretization, and Solvers under the modeling section for that physics. The interface is supported on all mesh types and for all combinations of mesh.

The Nonlinear Pressure Acoustics, Time Explicit interface is supports physics-controlled mesh. To get an appropriate mesh, remember to set the value of the Maximum frequency to resolve in the Transient Mesh Settings section. The automatically generated mesh will use this value and the speed of sound defined in the model to set up an appropriate mesh that follows the best practices. This is often a good mesh to use as a starting suggestion.
