Grid Challengesin Automotive Industry
SIMDAT SIMDAT Automotive
Grid Challengesin Automotive Industry
The challenge of integrating• different disciplines:
– Design (CAD)
– Simulation (CAE)
– Test (CAT)
• different locations
• different organisations
SIMDAT SIMDAT Automotive
Only the CAE engineer knows,which part is used and in which form it is
represented
Product Structure- Simulation Structure
CAD – CAE Integration
Situation:For build-up of a simulation model • structural information• geometric and• material datafrom CAD are needed
Structure differs from load case to load case Geometric representation of the parts differs
from load case to load case

Status:– CAD-CAE mapping of more than 80% of a car with 1500 parts
for NVH trimmed body– prototype with ontobroker realised– 35 rules only from structural information– in progress – search for more rules using more attributes

Audi use case forCAE/CAT integration:
• View and use CAT data inthe same manner as CAE data in the CAE data management system
SIMDAT SIMDAT Automotive
CAE (Simulation)
• Input Deck
• Model
• Design variant
• Load case
• Results
• Output files
• Post Process Objects
• Curves
• Animations
• Pictures
• Values
• Cross sequences
CAT (Test)
• Vehicle configuration
• Test case
• Measured results
• Sensor output files
• Channels
• Movies
• Measured Values
• Evaluation of measured results
• Curves

CAE System CAT System
HeterogeneousData Structures
1. CAE System formulates request according to own data model
2. Request is transformed into data model of the CAT system
3. CAT System answers request. The answer is transformed again and sent back
