How do I define the damping model in my vibro-acoustic analysis

The definition of damping in a vibro-acoustic model is crucial for predicting accurate results in simulations. However, getting information about the real damping of a structure is often a bottleneck, thus inducing high importance of having the right tools to define the damping in a model. This W...

How do I choose the BEM solver for my application and how can I parallelize my BEM solve

Boundary Element Analysis (BEM) is considered the industry standard for low frequency acoustic radiation however, the effectiveness of BEM is often constrained by the availability of computational resources capable of processing increasingly large models. VA One uses both classical BEM solvers and a...

How do I recover stress responses formed by sensitive space structures

A high intensity diffuse acoustic field surrounds a rocket during the initial launch stage. The intensity of this field is capable of compromising the integrity of composite fairings used to protect the payload and can also cause failure of composite components in space structures which form part of...

How can I predict flow induced noise in aircraft interiors

Flow induced noise is a major contributor to interior noise in aircrafts. This webinar will demonstrate how VA One can be used to model the effect of noise arising from interaction, from a surrounding during flight conditions using source models of turbulent boundary layer.

How can I build predictive high frequency automotive interior noise models

Vehicle interior noise is an important design aspect that is directly related to customer satisfaction. Accurate high frequency models are required to optimise the specification of noise control treatments in terms of cost, weight and noise effectiveness. VA One is the de facto standard for this typ...

How can I model interior noise in trains taking into account rail to wheel excitation?

Interior noise in rail passenger compartments is an important design consideration that directly relates to passenger satisfaction and driver safety. Our engineers will demonstrate how VA One can model passenger and engine compartments, taking into account complex floating floor sections comprised o...

How can I model thin and thick plate composites in VA One

VA One, the full-spectrum vibro-acoustic simulation software from ESI integrates deterministic and statistical vibro-acoustic analysis methods. This makes VA One the unique solution for vibro-acoustic simulation that covers the entire frequency range.

How can I model interior noise in Aircraft or Helicopter fuselage

Prediction of Interior noise level within an aircraft fuselage, arising from both induced flow and mechanical sources are an important aspect of aircraft design.  Let ESI VA engineers show you how vibro acoustic models can be quickly created from differing cabin layouts, predicting levels of interio...

How can I model underwater radiation

Underwater radiation is fast becoming an important aspect of marine design due to pressure from the environmental lobby to introduce legislation aimed at protecting both the marine environment and marine ecology. This webinar will demonstrate how VA One can be used to predict underwater radiation fr...

How can I model Muffler radiation taking into account flow and thermal effects

Ducts and mufflers come into contact with gases that flow through from source to the open environment. This flow exhibits a mean flow component and an acoustic pressure component which results in convected acoustic wave propagation. See how VA One working with an embedded OpenFOAM CFD solver can...
