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)

Set Flex Parts Inertia Mode

Benelux ADAMS User Meeting 2012 17

Change flex body Inertia Mode to directly compare to Rigid body results

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

Benelux ADAMS User Meeting 2012 18

Sample import from ProE Creo

Benelux ADAMS User Meeting 2012 19

May require some pre-

or postparation

Import on Part or in Model CAD Format Specific Parameters
