Abstract Submission deadline (extended): Monday 5th December 2022
Abstract submission: email: malcolm.druett@kuleuven.be with:
• a correspondence email address
• a presentation title
• an author list and affiliation details
• an abstract
• (optional) an image
Please keep abstracts to a reasonable length, such as those for journal publications. No hard word limit will be applied. We welcome applicants from the UK, but also around the globe. We encourage applications from early career researchers. We also highly welcome abstracts from members of under-represented groups in the field. If you require early travel planning (e.g. for a UK visa application), please state this in your submission and your abstract can be given early consideration.

Chairs: Dr Malcolm Druett (KU Leuven, Belgium), Dr Natasha Jeffrey (Northumbria University, UK)

Meeting Abstract: Solar flares are the result of many complex large and small scale plasma processes occurring in the Sun’s atmosphere. Driven by access to the latest generation of High-Performance Computing (HPC) services, higher dimensional models of solar flares are finally becoming feasible and a series of flagship 3D flare simulations have recently been published in high impact journals. Thus, we stand at a key point in time to evaluate and discuss the essential inclusions, assumptions, and simplifications in flare modelling. These will steer models made in the future, in terms of accurately reproducing physics and observational features from the upcoming generation of satellite, and ground-based observatories. In this meeting, we will highlight the fundamental differences in behaviours between higher-dimensional models and their lower dimensional counterparts. We will explore the benefits and drawbacks of different approaches applied in order to make 3D modelling feasible in the current era of computing. To do this, we solicit contributions covering complementary themes, designed to bring together important aspects of comprehensively modelling solar flares in 2D and 3D.
