'Dynamical energy analysis (DEA)' is a method for numerically modelling structure borne sound and vibration in complex structures in the mid-to-high frequency range.

It predicts the flow of vibrational wave energy across complex structures in terms of (linear) transport equations.

These equations are then solved on meshes.

Method
Statistical energy analysis

The energy flow is mapped onto a mesh using the Discrete Flow Mapping (DFM) technique .

The method determines the energy flux through interfaces – here the faces of the mesh elements. Reflection, transmission and mixing between different elastic wave modes at interfaces due to corners and changes in material parameters is included. The discretised flow equation is then transformed into a set of linear equations.
