While many software houses today propose virtual environments as yet another technological revolution, at Dassault Systemes, virtual has been a common thread for forty years. Since the French company launched advanced 3D design and then amrried it with prototyping, simulation, and finally virtual twins.

For Dassault, therefore, the virtual is extremely concrete. "Technology exists because it has a purpose, it doesn't exist in a vacuum", explains Olivier Ribet, Executive Vice President EMEAR at Dassault. And technology - in this case, simulation - must bring tangible value. Now the evolution from 3D to virtual twin goes a step further with the "virtual twin experiences". In short, simulating not only an object or a system but also the environment where it is embedded and the experiences of those who use it.

Virtual twin experiences are now an essential tool to address the most critical problems of our planet. Creating virtual twins of the ecosystems revolving around simple products, complex systems and entire organizations means being able to optimize them with simulations and development hypothesis. In a trial-and-error process that lives in the virtual space and gives us previously impossible margins for maneuver.

The development of anti-Covid vaccines is the best example of how simulation can be a game changer: doing in a few months what would normally have taken years of clinical trials. This experience needs to be extended everywhere if we really want to address the challenges we face - most notably, climate emergency mitigation - while gaining the one and only resource we cannot control: time.

It is no coincidence that Green Transition is now among the biggest growth drivers for Dassault. For example, "companies in the European energy sector are reinventing how their infrastructure is designed and built, moving away from models that date back some 20 years and are ill-suited to new scenarios", Ribet says. Then there is the growing European interest in hydrogen as an energy source. Or the aviation sector's willingness to phase out classic fuels and move to greener alternatives.

Sharing knowledge through simulation

These are all wide-impact technological evolutions, not easy to complete and certainly expensive. But they are also inevitable, because "the cost of not doing them is even greater", Ribet points out. The good news? "In Europe we have an immense concentration of knowledge that stem from millennia of design and engineering experience", Ribet explains. A knowledge that can be embedded into virtual twins, because they "describe not only the 'what' but also the 'how' and 'why' of an object or a complex system".

Integrating knowledge into virtual twins allows it to be preserved and shared. More importantly, it allows knowledge from different domains, which were clearly separated and had no effective way to converge, to be pooled. This new shared knowledge makes it possible to achieve relevant results quickly, addressing design and technical challenges that until recently would not have been feasible.
