Numerical modelling is explained in this collection of accurate, accessible science graphics, designed to make understanding complex Earth science simulations clear and engaging. These visuals show how computational models are used to study processes such as plate tectonics, mantle convection, and subduction, turning abstract data into intuitive, easy-to-grasp representations. Ideal for educators, students, and geoscience enthusiasts, this numerical modelling graphic collection brings cutting-edge geoscience research to life with visually rich resources for teaching and learning.
Numerical discretisation (domain & material)
Examples of numerical, two-dimensional domain and material discretisation.
Governing equations
The governing equations of numerical modelling include conservation of mass, momentum, and energy with different types of rheology.
Computing
Different computation paradigms including sequential and parallel programming each with the corresponding discretised domain.
Numerical discretisation (space & time)
One-dimensional discretisation in space and time based on discrete temporal and spatial steps.
3-D subduction mantle flow
3-D subduction dynamics and mantle flow model animation showing the time evolution of oceanic plate subduction and resulting mantle flow.
Deformation mechanisms
The three deformation mechanisms viscous, elastic, and brittle (a.k.a. plastic).
Plume-induced subduction
Temporal evolution of subduction initiation in a global, 3-D spherical numerical experiment showing the cold plates and hot mantle plumes.
Geodynamic scales
Spatial and temporal scales of common geodynamic processes, which occur over a wide range of time and length scales.
