Grid Challengesin Automotive Industry


Grid Challengesin Automotive Industry

The challenge of integrating• different disciplines:

– Design (CAD)

– Simulation (CAE)

– Test (CAT)

• different locations

• different organisations


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

Selection of detected rules:– Structure parts are parts with the middle group number

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


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

• Images

• Values



CAE System CAT System


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
