Modified-gradient methods for exact divergence-free in meshless magnetohydrodynamics
Xiongbiao Tu, Qiao Wang, Liang Gao +1
We present a novel gradient regularization to completely eliminate the magnetic divergence error in meshless magnetohydrodynamics (MHD), which offers a high spatial resolution and…
Symplectic Integrators in Corotating Coordinates
Xiongbiao Tu, Qiao Wang, Yifa Tang
The dynamic equation of mass point in rotating coordinates is governed by Coriolis and centrifugal force, besides a corotating potential relative to frame. Such a system is no long…
Meshless Methods for Magnetohydrodynamics with Vector Potential
Xiongbiao Tu, Qiao Wang, Haonan Zheng +1
We present a meshless method for magnetohydrodynamics by evolving the vector potential of magnetic fields. A novel scheme and numerical techniques are developed to restrict the div…
Symplectic methods for non-canonical Hamiltonian systems
Beibei Zhu, Ruili Zhang, Yifa Tang +1
We show that, when applied to any non-canonical Hamiltonian system, any integrator that is symplectic for canonical Hamiltonian problems is actually conjugate symplectic for the no…
