Accelerating Simulation of Two-Phase Flows with Neural PDE Surrogates

no code implementations27 May 2024 Yoeri Poels, Koen Minartz, Harshit Bansal, Vlado Menkovski

Simulation is a powerful tool to better understand physical systems, but generally requires computationally expensive numerical methods.

Efficient Probabilistic Modeling of Crystallization at Mesoscopic Scale

1 code implementation26 May 2024 Pol Timmer, Koen Minartz, Vlado Menkovski

In this paper, we introduce the Crystal Growth Neural Emulator (CGNE), a probabilistic model for efficient crystal growth emulation at the mesoscopic scale that overcomes these challenges.

Fast Dynamic 1D Simulation of Divertor Plasmas with Neural PDE Surrogates

no code implementations30 May 2023 Yoeri Poels, Gijs Derks, Egbert Westerhof, Koen Minartz, Sven Wiesen, Vlado Menkovski

State-of-the-art neural PDE surrogates are evaluated in a common framework and extended for properties of the DIV1D data.

Equivariant Neural Simulators for Stochastic Spatiotemporal Dynamics

1 code implementation NeurIPS 2023 Koen Minartz, Yoeri Poels, Simon Koop, Vlado Menkovski

However, to incorporate symmetries in probabilistic neural simulators that can simulate stochastic phenomena, we need a model that produces equivariant distributions over trajectories, rather than equivariant function approximations.

Towards Learned Simulators for Cell Migration

no code implementations2 Oct 2022 Koen Minartz, Yoeri Poels, Vlado Menkovski

Simulators driven by deep learning are gaining popularity as a tool for efficiently emulating accurate but expensive numerical simulators.
