A high-order Newton multigrid method with a simplified Jacobian for steady-state shallow water equations
Zhicheng Hu, Guanghan Li, Chunwu Wang +1
A high-order Newton multigrid method is proposed for steady-state shallow water flows in open channels with regular and irregular geometries. The method integrates a finite volume…

A novel fast iterative moment method for near-continuum flows
Guanghan Li, Chunwu Wang, Zhicheng Hu
We develop a novel fast iterative moment method for the steady-state simulation of near-continuum flows, which are modeled by the high-order moment system derived from the Boltzman…
