LMS Virtual.Lab, is an integrated suite of 3D FE and multibody simulation software which simulates and optimizes the performance of mechanical systems for structural integrity, noise and vibration, system dynamics and durability.

LMS Virtual.Lab software features an integrated computer-aided engineering (CAE) suite for accurate simulation and optimization of mechanical system performance for structural integrity, noise and vibration, system dynamics and durability. The software allows you to define processes covering several attributes simultaneously, including parametric analysis. This enables fast assessment of multiple design alternatives and optimization prior to physical prototype construction. Embedded in a computeraided design (CAD) platform and interfacing very well with various CAE solvers and testing software, LMS Virtual.Lab holds a central position in every step of the development process.

LMS Virtual.Lab is part of the LMS solutions portfolio of product lifecycle management (PLM) specialist Siemens PLM Software, which also features a high-end finite element (FE) solver suite, LMS Samtech software; a multi-domain system simulation platform, LMS Imagine.Lab software for testing; LMS Test.Lab software and data acquisition frontends from the renowned LMS SCADAS hardware family. These software and hardware solutions are complemented by LMS Engineering services, offering consultancy services ranging from troubleshooting to technology transfer projects, co-development and full program management.

Acoustics and Vibration

The unique high performance finite element model adaptive order (FEMAO) acoustic solver embedded in LMS Virtual.Lab Acoustics software automatically adapts element order to enable full frequency range acoustic analysis on a single FEM mesh precisely and efficiently. LMS Virtual.Lab Acoustics 13.7 also enables you to perform scalable noise analysis adapted to your product development processes. For aero-acoustic problems, LMS Virtual.Lab Acoustics provides a high performance algorithm to handle terabytes of data produced by computational fluid dynamics (CFD). The algorithms integrated in LMS Virtual.Lab Acoustics 13.7 enable more efficient handling of larger sets of CFD data and achieves higher accuracy of final predictions.

Mechanisms

Coupling of multibody simulation (MBS) software – LMS Virtual.Lab Motion – and a nonlinear finite element analysis (FEA) solver – LMS Samtech Samcef Mecano – enables accurate representation of nonlinear component deformations by accounting for large deformations and nonlinear material properties. LMS Virtual.Lab Motion 13.7 embeds a nonlinear FEA solver to accurately predict nonlinearity and enhances the 1D/3D real-time solution which provides accurate 1D and 3D simulation models for hardware-in-the-loop and driving simulators.

LMS Virtual.Lab Durability enhances CAE process integration with an editable text-based file that contains all model and solver job information. LMS Samtech Tea Pipe enables cost-effective material characterization of pipes and hoses.

Automotive Process Integration

LMS Virtual.Lab Structures is an efficient and fully featured pre/postprocessing environment to perform linear, nonlinear and crash analysis on components, subsystems and full vehicles. The unique generic assembly environment allows you to create solver and attribute independent assemblies which can then be automatically fed to different solvers (such as Nastran, Radioss, Abaqus and LS-Dyna) and attributes (such as static strength, durability, crash and safety). Open and customizable, LMS Virtual.Lab software provides the foundation to automate and streamline vehicle assembly for noise, vibration and harshness (NVH), durability and crash.
