The Transient Mapping (

) study is a dedicated study to use when the 
Aeroacoustic Flow Source Coupling couples a LES 
Fluid Flow interface with the 
Aeroacoustic Flow Source in pressure acoustics. The study should only solve for the multiphysics coupling. The study uses a tailored 
Transient solver. Together with the multiphysics coupling, the study handles the mapping of flow source variables (the Lighthill stress tensor) between the fluid flow mesh and the acoustics mesh for consistent simulation results.
