4.2.1 Best Practice Topics Covered Within Working Area Integration
• CAD-Integrated CAE Tools
A broad range of CAD-integrated CAE tools have been developed
and delivered to the market in recent years. CAD-integrated CAE
works especially well (time reduction) on a component level and for
certain analysis types (commodity).
It should be noted that the CAD-integrated software created for
initial testing simulations does not always provide the fully accurate
picture which can only be obtained from detailed simulation. Nor
can all the constraints be considered, causing a bottleneck. A
strategy of simulation-driven concept design, as described in
Section 4.2 above, is considered a viable solution for overcoming
this problem.
• Simulation Data Management / Product Data Management
(SDM/PDM)
The role of SDM is to capture and manage data, process, and
methods, which differentiates it from existing Product Data
Management (PDM) solutions. Best Practice today is to use PDM
and SDM systems in parallel. PDM systems of today manage
(frozen) data for the product, whereas SDM systems manage data
(geometry, model, result) history and process to accommodate
virtual product development. A bi-directional link between PDM and
SDM is important, as product meta-data are held in PDM. The basis
for this link could be a hierarchical product documentation covering
PDM as well as SDM systems, combined with corresponding
hierarchical data mining models. It is expected that today’s PDM
and SDM systems will be consolidated into one system in the future
(Breakthrough Technology).
One approach for this consolidation is provided by the ProSTEP
project group „SimPDM“ with the project „Integration of Simulation
and Computation in a PDM Environment “.
(www.prostep.org/en/projektgruppen/simpdm/). This group has the
objective of developing a specification in order to integrate CAE-
Systems into a PDM-Environment (Fig. 4.2.1.1).
The standardized, generic meta data model for simulation and
computation data can be integrated into any PDM-System.
Therefore simulation and computation data are managed within the
existing PDM system. Another advantage is the parameter
synchronization between product structure and CAE model
