Fujitsu and partners automate parameter tuning for solar energetic particle simulations

Fujitsu, Nagoya University, JAMSTEC and NICT developed the first technology that automatically determines simulation parameters for solar energetic particle (SEP) arrival using observations from five spacecraft, including BepiColombo. The SEITEN system uses black-box optimisation to set 19 parameters, coupling the SUSANOO MHD model with the SEPIF particle transport model; results were published in Scientific Reports.

• SEITEN automatically tunes 19 SEP simulation parameters from five spacecraft datasets
• The technology couples the SUSANOO MHD model with the SEPIF particle model
• Results were published in the journal Scientific Reports
• Aims to protect astronauts from radiation and cut satellite failures
