Motion
LMS Virtual.Lab Designer Motion
Rigid-body system dynamics and “flexible bodies”
(dynamic displacement and stress during motion),
fully integrated in CATIA V5
 Extends CATIA Kinematics with complete system dynamics
Forces and moments too instead of just displacement and its
derivatives like velocity and acceleration
 Simulation of complex motions and accurate calculation of
often difficult-to-measure forces and moments
 Dynamic displacement and stress within components during
motion through “flexible bodies” option and GPS/ELFINI
 Automatic calculation of forces and moments for design
purposes or subsequent fatigue and acoustic analyses

LMS Virtual.Lab Designer Fatigue
Component strength and fatigue analyses under
varying force and moment load conditions and
different materials, fully integrated in CATIA V5
 Automatic input and editing of force and moment load data
 Calculation via Virtual.Lab Designer Motion
 Raw test data
 Seamless integration with finite-element meshes generated
by CATIA CAE (GPS, GAS, FMS)
 Accurately predicts component strength and fatigue
performance before expensive prototype builds and lengthy
test cycles

Acoustics
LMS Virtual.Lab Designer Acoustics
External and internal acoustic simulation capabilities,
fully integrated in CATIA V5
 Two possible options
 “Boundary Element Method” or “BEM” for external
acoustic simulations
Example: radiated sound field (far field) in free space
emanating from external vibrating surfaces
 “Finite Element Method” or “FEM” for internal
acoustic simulations
Example: radiated sound field (standing field) in an
enclosed volume surrounded by vibrating
surfaces
 Maintains complete associativity with CATIA CAD geometry
 Visualization of sound pressure levels in a variety of formats

LMS Virtual.Lab Designer (or any CAE Software Suite)…
 is not a “black box” with immediate and completely accurate design solutions
 cannot and indeed shoud not be used to obtain “exact” and “absolute” results
 is no substitute for technical skills, experience, and education
 is absolutely not a substutite for rigourous testing
 in all cases requires user attention and responsibility while building models and
analyzing results
