Our team members Oriol Fernández and José Lorenzo attended the 7th International Workshop on Numerical Modelling of High-Temperature Superconductors from 22nd to 23rd June. The event was planned to be held in Nancy, France, in 2020 but due to the current pandemic situation it had to be postponed and finally took place remotely in 2021.

This workshop is held every two years with a mini-conference format and constitutes an excellent opportunity for the High-Temperature Superconductivity (HTS) community to gather and share their latest progress in the research and development of modelling tools for Applied Superconductivity.  The contributions were arranged in talks and poster sessions, and covered three main categories: Modelling Fundamentals, Coupled & Uncoupled Multiphysics Problems, and Applications. Moreover, an interesting lecture on aviation decarbonization at Safran was presented given the potential contribution of HTS in this subject.

HTS Technology shows promise for the next generation of fusion reactors based on magnetic confinement as it enables higher current densities and magnetic fields compared to Low Temperature Superconductors. In collaboration with ICMAB within the FusionCAT project, our Fusion group at BSC is developing an electromagnetic code to model HTS applications making use of advanced High-Performance Computing (HPC) techniques. This software is built as a new module integrated in the HPC platform Alya. The module implements the H-Formulation of Maxwell’s equations and the Edge Finite Element Method to compute magnetization and AC losses in HTS tapes. The goal is to eventually provide an HPC tool able to address the multiphysics simulations of relevant phenomena that occur is superconducting devices, such as quench (transition to the normal resistive state), by coupling this electromagnetic code to other currently existing modules that solve Heat Transfer or Solid Mechanics. Indeed, tools for HTS modelling able to run on supercomputers were given attention in some of the workshop contributions as they are essential to tackle multiphysics in large and complex geometries.

We want to thank the organizers for going ahead with the workshop as the event run smoothly in spite of the complex situation. In particular, we would like to highlight the excellent organization and format of the poster session, with separate Zoom rooms accessible from the main channel where the attendees could easily interact with the presenter.

The workshop program as well as the posters can be accessed here.

The FusionCAT project is co-financed by the European Union Regional Development Fund within the framework of the ERDF Operational Program of Catalonia 2014-2020 with a grant of 50% of total cost eligible.
