This presentation by Danilo Di Stefano was made at the NAFEMS eSeminar "Simulation & Digital Twins - Behind the Buzzwords" on the 2nd of May 2018.

Metamodelling techniques speed up the search for promising designs by replacing computationally expensive design evaluations or simulations. They provide a global model of some design response, which can then be optimized efficiently.  

As, in the context of digital transformation, simulation is expected to spread all over the product lifecycle, metamodelling techniques too will be requested to adapt to different types of data and to exploit different types of predictive capabilities. In this presentation, the role of metamodelling in digital transformation will be discussed, with examples and challenges to be addressed.
