HiDALGO participated in an online conference on 11-12 June 2020 on “Multiscale Modelling, Uncertainty Quantification and the Reliability of Computer Simulations”, with a total of five talks spanning all the pilot application domains. The conference was attended by more than 250 people, and is a combination of three events that were due to take place at the SIAM Conference on Uncertainty Quantification (UQ20) and the International Conference on Computational Science (ICCS) 2020, but were cancelled due to the COVID-19 pandemic.
