Flash-X, a multiphysics simulation software instrument
Anshu Dubey, Klaus Weide, Jared O'Neal +28
Flash-X is a highly composable multiphysics software system that can be used to simulate physical phenomena in several scientific domains. It derives some of its solvers from FLASH…
Hydrodynamics and survivability during post-main-sequence planetary engulfment
Ricardo Yarza, Naela Razo Lopez, Ariadna Murguia-Berthier +6
The engulfment of substellar bodies (SBs, such as brown dwarfs and planets) by giant stars is a possible explanation for rapidly rotating giants, lithium-rich giants, and the prese…
GP-MOOD: A positive-preserving high-order finite volume method for hyperbolic conservation laws
Rémi Bourgeois, Dongwook Lee
We present an a posteriori shock-capturing finite volume method algorithm called GP-MOOD that solves a compressible hyperbolic conservative system at high-order solution accuracy (…
A recursive system-free single-step temporal discretization method for finite difference methods
Youngjun Lee, Dongwook Lee, Adam Reyes
Single-stage or single-step high-order temporal discretizations of partial differential equations (PDEs) have shown great promise in delivering high-order accuracy in time with eff…
A Global Non-Hydrostatic Atmospheric Model with a Mass and Energy Conserving Vertically-Implicit-Correction (VIC) Scheme
Huazhi Ge, Cheng Li, Xi Zhang +1
Global non-hydrostatic atmospheric models are becoming increasingly important for studying the climates of planets and exoplanets. However, such models suffer from computational di…
A single-step third-order temporal discretization with Jacobian-free and Hessian-free formulations for finite difference methods
Youngjun Lee, Dongwook Lee
Discrete updates of numerical partial differential equations (PDEs) rely on two branches of temporal integration. The first branch is the widely-adopted, traditionally popular appr…
