  Information - TS1.1 The strengths and challenges of analogue and numerical models (co-listed in GD)

Event Information
Analogue and numerical modelling techniques are being utilised more extensively in recent years to study processes in Earth's crust and mantle. The modelling methods are partly overlapping and partly of a complementary nature, whereby both have their strengths and weaknesses. Analogue, or physical, models have traditionally been strong in visualising the mechanical behaviour of processes in 3D, but remain limited in their ability to quantify observables or use more complicated material rheologies. These can be better achieved by numerical models, but their 3D resolution is only improving slowly. The aim of this session is to focus on analogue and numerical models and provide room for the discussion of their limitations, challenges and roles in the near future. We welcome contributions that discuss modelling and visualisation techniques, use models to quantify Earth behaviour, compare analogue and numerical model results to each other and/or to examples from nature, on the scale of the crust to the mantle, for both 2D and 3D.
