Ice melting in an oscillatory flow
Sofía Angriman, Tobias de Buck, Roberto Verzicco +1
We investigate the melting dynamics of an ice disk subjected to an external oscillatory flow using two-dimensional direct numerical simulations, in the absence of buoyancy, varying…
Per Astronomix ad Astra: High-Order Differentiable (Magneto)hydrodynamics with Energy-Conserving Self-Gravity
Leonard Storcks, Nils Thuerey, Tobias Buck
We present astronomix, a performant differentiable (magneto)hydrodynamics simulator written in Python/JAX. We demonstrate how automatic differentiation, validated against hand-deri…
Solver-in-the-Loop Applications in Astrophysical (Magneto)hydrodynamics
Leonard Storcks, Tobias Buck
We present two promising applications of training machine learning models inside a differentiable astrophysical (magneto)hydrodynamics simulator. First, we address the problem of s…
Differentiable Conservative Radially Symmetric Fluid Simulations and Stellar Winds -- jf1uids
Leonard Storcks, Tobias Buck
We present jf1uids, a one-dimensional fluid solver that can, by virtue of a geometric formulation of the Euler equations, model radially symmetric fluid problems in a conservative…
