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).

Arbitrarily 3D shaped surfaces

This paper illustrates the modeling process to be applied by a Visual-Mesh user with the objective of creating one arbitrarily 3D shaped surface starting from scratch.

How to fill multiple holes of different shapes and sizes on a plate?

Using Visual-Mesh, you can fill small holes of different diameters with a surface easily. This can be achieved with the Surface Trim option available in the surface menu.

How does Batch Mode execution work in Visual-Environment?

To run the scripts in Batch mode

How to filter entities in the Explorer?

You can filter entities based on Name and ID and also list the referred entities

How to create your own toolbars in Visual-Environment?

You can create your own toolbars using Tools->Customize

How to change user home location in Visual-Environment?

You can change the Home and Temporary directory path from General Preference or from the Variables

How to make an advanced selection in Visual-Environment?

Advanced Selection allows you to select entities in different ways such as column wise, sheet wise, etc. It also allows you to stop the selection at non manifold T-Sections based on feature angle.
