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).
