Accelerating the discovery of steady-states of planetary interior dynamics with machine learning

no code implementations30 Aug 2024 Siddhant Agarwal, Nicola Tosi, Christian Hüttig, David S. Greenberg, Ali Can Bekar

Consequently, achieving steady-state requires a large number of time steps due to the disparate time scales governing the stagnant and convecting regions.

ExoMDN: Rapid characterization of exoplanet interior structures with Mixture Density Networks

1 code implementation15 Jun 2023 Philipp Baumeister, Nicola Tosi

The model is trained on a large dataset of more than 5. 6 million synthetic planets below 25 Earth masses consisting of an iron core, a silicate mantle, a water and high-pressure ice layer, and a H/He atmosphere.

Deep learning for surrogate modelling of 2D mantle convection

no code implementations23 Aug 2021 Siddhant Agarwal, Nicola Tosi, Pan Kessel, Doris Breuer, Grégoire Montavon

Using a dataset of 10, 525 two-dimensional simulations of the thermal evolution of the mantle of a Mars-like planet, we show that deep learning techniques can produce reliable parameterized surrogates (i. e. surrogates that predict state variables such as temperature based only on parameters) of the underlying partial differential equations.

Settling of inertial particles in turbulent Rayleigh-Benard convection

1 code implementation11 May 2020 Vojtech Patocka, Enrico Calzavarini, Nicola Tosi

The settling behaviour of small inertial particles in turbulent convection is a fundamental problem across several disciplines, from geophysics to metallurgy.
