An improved estimate of the intermediate internal energy in the energy-consistent HLLD scheme
Fan Zhang
The paper introduces a simple correction to the intermediate internal energy estimate in the HLLD approximate Riemann solver for magnetohydrodynamics, improving robustness and pres…
COCONUT: Toward practical time-evolving Sun-to-Earth magnetohydrodynamic modeling
Haopeng Wang, Stefaan Poedts, Andrea Lani +16
Due to computational efficiency and numerical stability limitations, coronal simulations constrained by static magnetograms are typically performed first and then used to drive inn…
Time-evolving coronal modelling of the solar maximum around the solar storms in May 2024 by COCONUT
Haopeng Wang, Stefaan Poedts, Andrea Lani +8
Time-evolving MHD coronal models deliver more realistic results than traditional quasi-steady-state models. The fully implicit time-evolving coronal model COCONUT performs efficien…
On energy consistency of intermediate states in HLL-type MHD Riemann solvers
Fan Zhang, Andrea Lani, Stefaan Poedts
Approximate Riemann solvers are widely used for solving hyperbolic conservation laws, including those of magnetohydrodynamics (MHD). However, due to the nonlinearity and complexity…
