Earth Modelling: Numerical models of Earth Dynamics

Numerical modeling is a prime tool for studying Earth evolution and dynamics. Using external and in-house codes, programs and databases, CEED researchers perform numerical models ranging from simple 2D axi-symmetric studies to massively parallel 4D global simulations. Our overlying mission is to integrate tectonic plate reconstructions into global 4D geodynamic and climate models. Within this goal, we aim to develop cost- and time-efficient modeling and visualisation platforms that will aid in Earth evolution reconstructions.

Centre: a numerical convection model of a degree-1 mantle structure with one single large upwelling (LLSVP) beneath Africa. Right: a numerical convection model showing the present-day temperature structure (red=hot) resulting from a thermochemical calculation investigating the effect of initial temperature condition on the formation of LLSVPs.

The interdisciplinary nature of CEED provides an ideal research environment for multi-system numerical models. Using inputs from a great diversity of disciplines, including geology, physics, mathematics, chemistry, palaeoclimatology, palaeontology, tectonics, palaeomagnetism, geodynamics, seismology, mineral physics, planetology and atmospheric sciences, CEED researchers want to perform numerical models which enable analysis and interpretation of biological, geological, climate, geographical and dynamical data in time and space. 

Supported by the Norwegian Metacenter for Computational Science (, CEED researchers aim to work on a variety of geodynamical problems whilst building upon both external and internal codes and databases.
