Fig. 4.5.2.1: Simulation Data and Process Management (courtesy of MSC<br />
Software)<br />
Fig.4.5.2.1 shows a sample process map of a generic crash simulation<br />
process with both simulation data objects (green circles) and simulation<br />
process actions (blue boxes). SDM should manage the simulation data, and<br />
also offer the possibility of managing the simulation processes. This is<br />
particularly important for increasing confidence in simulation data, as it<br />
makes simulation processes repeatable and, thus, results easier to<br />
compare. It should be noted that, especially in early design phases,<br />
appropriate CAD data may not be available yet. For this reason any SDM<br />
system must be flexible enough that input data for building simulation<br />
models can come from different sources, not necessarily from PDM<br />
systems only, but of course desired in the future.<br />
To enable a total procedure to become faster, an integrated software<br />
environment is needed. For example, the physical layout needs to be done<br />
rapidly either using CAE or (semi-)analytically or with symbolic CAE when<br />
only some basic data is available (Fig.4.5.2.2).<br />
Very often in a typical new vehicle, in order to encourage design work using<br />
CAE during early development phases, parametric vehicle-concept models<br />
are desirable because they allow conceptual, geometric modifications to be<br />
evaluated rapidly at a time when no CAD data is yet available. Such tools<br />
should allow concept modification cycles (i.e. variation of parametric vehicle<br />
concepts) on data available either from predecessor models or from scratch<br />
(Fig 4.5.2.2).<br />
