Software claims breakthrough system-level CAE
The latest release of LMS Virtual.Lab offers an integrated environment to engineer key performance attributes such as noise and vibration, durability, ride and handling.
LMS Virtual.Lab will increase the efficiency of Renault's acoustic modelling and computation procedures, and will reduce the time and cost of their design processes.
Vehicle refinement and vibroacoustic comfort have always been important in Renault's strategy of developing distinctive and superior vehicles.
To achieve higher levels of acoustic comfort within shorter development times, Renault began to explore how to address acoustic performance early in the process.

LMS Virtual.Lab Acoustics dramatically accelerates the acoustic modelling process at Renault.
Creating an acoustic mesh starting from a structural model used to be a lengthy, manual process.
LMS Virtual.Lab applies a completely new meshing method.
It "wraps" a structural FE model and reduces the amount of detail to the level needed for the acoustic simulation.
The smaller size of the model means that acoustic calculations are much faster than before, and that more designs can be evaluated.
Renault also chose LMS Virtual.Lab for its improved acoustic solver.
It delivers fast, efficient calculations that are especially useful for multiple engine speeds, and for assessments of the complete engine during run-up.
The LMS Virtual.Lab solver is so fast that acoustic simulations will now become a regular part of the development process at Renault.
With LMS Virtual.Lab, Renault will be able to quickly assess the virtual behaviour of their engines because of the easy mesh preparation and the effectiveness of the acoustic calculations.
Renault engineers liked the quality and the integration of the functions and tools - covering the complete engine vibroacoustic process - as well as the sheer speed of the remeshing and simulation steps.
M Bernard, head of Renault's research department says: "LMS Virtual.Lab has reduced the time we used to waste in converting from a structural to an acoustic power train model, from several days per model, down to a few hours". Request a free brochure from LMS International ...
