EURAD-2 - D16.1 State-of-the-art on high fidelity numerical simulations of strongly coupled processes for repository systems (Initial report)

This initial State-of-the-Art report describes the major coupled T-H-M-C processes in geological repository systems and the frontier of related model development. Particular focus is placed on the analysis of existing approaches and open research questions with respect to further developments of coupled codes and models for realistic multi-scale simulation of repository systems. These include the use of machine learning and artificial intelligence for the acceleration of computer codes; sensitivity analysis, inverse modelling and optimisation; software engineering and collaborative platforms for model development. By the end of the WP-HERMES, this report will be complemented with the knowledge acquired during the course of the WP HERMES RD&D program.
