Cat McClintock in the blog “[Study] 3 Eye-Opening Business Results from Simulation-led Design” discusses about the following

Simulation-led design is an approach to product development in which engineers analyze their work during the design phase. That is, they use tools built into their CAD system to ensure their models pass basic structural, thermal, and modal tests. These tests, in turn, inform the hundreds of decisions designers make, as they’re making them.

It’s a revolutionary idea because, typically, companies follow a more step-based process: Design first, then send the work to the analysis department. There, analysts may import the model into full-fidelity analysis software and then send a report back to designers. Designers use the data to update the model in their CAD system, and so on.
