SEA - Display energy flow for a subsystem in complex models
In a complex SEA model made out of several subsystems, VA One can be used to display the energy flow to a particular subsystem in a couple of steps, this helps to understand how the energy flows to a receiving subsystem in order to define noise control strategies. One of the steps is to isolate the junctions associated to this subsystem, this will also help to understand / verify the connectivity of the model.

SEA - Virtual Transmission Loss
In a complex SEA model made out of several subsystems, using VA One is possible to extract the transmission loss (TL) of one or various subsystems in a single step. Transmission loss of partitions e.g. walls, floor, windows, enclosures have been studied theoretically and experimentally over many years. Partitions are often inhomogeneous, non-uniform, comprise combinations of different materials, have indeterminate boundary conditions and are subject to sound complex fields. Surprisingly the sound transmission behavior of many plane partitions is quite well represented by a simple model which ignores the boundaries. Sound transmission loss can be used to correlate the vibro-acoustic behavior of simple and/or complex systems.

VA One - FE or SEA- How to map trim thickness for sound package representation
Sound control treatments / Trim ,(e.g. headliners,hood liners, dash panel and floor isolators, etc) have complex shapes with variable thickness, sometimes only CAD parts are available. How can I use this data to create noise control treatments (NCT) in FE and/or SEA models with variable thickness?. In this article it is shown how to create a variable thickness noise control treatment with VA One for SEA and/or FE purposes at the same time. A multiple noise control treatment (MNCT) is created for SEA purposes and multiple FE Faces with the mapped/discrete thicknesses are created for FE purposes,

Find dominant path in SEA models
Statistical energy analysis (SEA) computes the flow of vibrational energy between coupled subsystems by applying principle of conservation of energy. Using conservation of energy power balance equations which govern response of a system. Since it is based on energy flow, path analysis is straight forward. In this article it is described how to extract the dominant path in a complex model using SEA and VA One . As a result the subsystems in the dominant path are displayed in the 3d window (All other subsystems are hidden).

Coupling between PAM-FORM and PAM-RTM: multiple part mapping
Coupling between PAM-FORM 2G and PAM-RTM is done through a .DSY file. Thus, pre-forming process is simulated with PAM-FORM 2G and resulting fiber orientations that will affect permeabilities are transferred to PAM-RTM model setup.
