Designing the whole

Connecting model-based system engineering through PLM tools to CAD, FEA, and physical test is on the horizon.
System-level modeling and simulation- tools for complete vehicle behavior-are about to expand, according to Derek Wright, Product Manager for
The collaboration net will need to expand beyond engineering. “We are moving towards bidirectional connectivity with the CAD environment, for example. That is going to be very important in the future,” he says. Why? According to him, using CAD to create simplified models for system-level models is vital to tame computational complexity. Computational complexity is nonlinear; only simplified models can compute a solution in a reasonable time. For example, so-called lumped-parameter models simplify a mechanical system to its essence. “You need to use CAD to create lumped-parameter models without losing the connectivity if you adjust the system model,” he explained. “The CAD guy does not want to know the lumped-parameter model. The lumped-parameter guy does not want to know all of the CAD detail. We need one model that I can look at with different lenses.”
