ESI VA One 2020.1

The virtual prototyping software provider ESI Group is pleased to announce the availability of VA One 2020.1 is a single environment for vibro-acoustics analysis and design.

What's new in ESI VA One 2020.0

ESI VA One 2020.0 contains several enhancements and new features to improve the modeling and simulation experience for its users across a wide range of industries, applications and methods. The new enhancements enable VA One to even more efficiently support design and simulation to meet acoustic and vibration targets and standards.

VA One 2020.0 Main Enhancement Highlights:
- Improved Ray Tracing performance and results visualization, particularly for models with diffraction
- Modernized and Enhanced 3D Window and Plotting
- Improvements to performance and accuracy of PEM solver
- Automated functionality to "fill" holes in model geometry
- Inclusion of ESI scalable VPS FE solver (for tokens users only, available as separate module for non-tokens users)
- Several corrections and fixes


ESI VA One is a single environment for vibro-acoustics analysis and design. It allows engineers to perform accurate predictive noise and vibration design assessments early in the design cycle to meet product performance objectives.

VA One is used by manufacturers across the globe to predict and resolve potential noise and vibration problems up front in their development process, so they can deliver more competitive products and comply with tougher noise regulations.

VA One is the only software solution on the market that enables the simulation of noise and vibration across the full frequency range by seamlessly combining key vibro-acoustic modeling methods: Finite Elements (FEM), Boundary Elements (BEM), and Statistical Energy Analysis (SEA) in a single model.

VA One allows engineers to get a precise idea of a product’s future vibro-acoustic performance by setting up interior or exterior acoustic models, coupled if necessary with a vibrating structure having various types of excitations.

Furthermore, VA One now enables engineers to couple BEM and FE cavities. This allows, for example, the simulation of a duct radiating noise externally; a situation relevant to investigating the noise from HVAC (heating, ventilation, and air conditioning) systems or automotive exhausts.

VA One provides the perfect environment to support all types of VA simulation needs – from checking early design concepts through the detailed component design phase, to troubleshooting in the virtual qualification test phase. It can also be used for product cost and weight optimization by simulating various sound package scenarios, while preserving product specifications.

New release of VA One 2020, added several enhancements and new features to improve the modeling and simulation experience for its users across a wide range of industries, applications and methods. The new enhancements enable VA One to even more efficiently support design and simulation to meet acoustic and vibration targets and standards.
