2012: New GUI Look and Feel
Benelux ADAMS User Meeting 2012 3
Ribbon Bar
Model Browser
Status Toolbar
2012: New GUI Look and Feel
� Ribbon Bar: intuitive usage: modelling
process from left to right
� Model Browser: ease of use and
powerful filtering / groupingBenelux ADAMS User Meeting 2012 4

Ribbon bar & Model Browser
� All database entities
available
� Object visibility
indication on Browse
tab
� Dynamic search based
on keywords
� Context menu (right
mouse button) in MB:
all object actions can be
executed directly
Benelux ADAMS User Meeting 2012 5
Model Browser� Tabs for Objects,
Groups and Filters
� New filters an easily be
defined, i.e. compare
to ADAMS Select List
� Groups can be defined
directly from Filters
� Groups: for visuals,
(de)activation etc. etc.
� Undocking of MB

ADAMS ViewFlex
� Create Flexible bodies inside A/View & A/Car in stead of FEA code
� Embedded meshing functionality and MSC Nastran solving
functionality
� Creates Modal Neutral File according to Craig Bampton method
� Features:
� Automatic or user defined meshing parameters
� Mesh Preview to check and improve meshing quality
� RBE2 (rigid connected nodes) & RBE3 (weighted balanced nodes) FEM elements are available to define slave nodes on a master interface Node
� Automated detection of Model connections for conversion to Flexible Body
Benelux ADAMS User Meeting 2012 7
Typical Modelling Process
� Start with Rigid ADAMS Model
� Define Connections and do Test & Reference Runs
(Crawl-Walk-Run)
� Use ViewFlex to Convert Rigid bodies to Flexible
� Simulate model with Flexible Bodies, requires
ADAMS/Flex
� Analyse stress and strain, requires ADAMS/Durability

MNF Conversion Process
� MESH
� � FEM Model
� � Craig-Bampton Reduction
� � Constraint Modes + Fixed Boundary Modes
� � Mnf File � ADAMS
� � Mode Orthogonalisation:
� Free-Free Modes
� Vibration Modes
� Residual Modes (in case of Flex Body Contact)

New CAD Import Possibilities
� Native Import of CAD Data:� Existing: Parasolids, IGES, STEP,
STL, ACIS
� Extra: Catia, Inventor, ProE,
SolidWorks, Unigraphics
� Requires ADAMS CAD Translators
License
� One way CAD translation, typical
then stored as Parasolids
