In recent years, the field of computational geoscience has accelerated with the advances in computing, putting into reach the ability to model the Earth's entire mantle and the crust at the scale of meters, for example. Thus the development of novel models, invoking the right level of abstraction in the physics, and the implementation of efficient numerical schemes are sought after in the field. In geophysical modelling, the ability to test the models with laboratory analogues is limited. Parameters are difficult to define, particularly since they can only be measured under present-day conditions, but may be applied as time-dependent in a model. The large variation in time and length scales, from the micro-second to hundreds of millions of years and from the nano-scale to the planetary scale further complicate the development of models: for which scales do certain assumptions behind the model hold.

For this session, we invite papers dealing with computational and algorithmic problems in the fields of geoscience: in particular from the fields of mathematical geology, geophysics, basin dynamics, geodynamics, planetary physics and porous media flow will be considered. Papers may present innovative models, methods or the problem of constraining models with data.
