On Well-posed Boundary Conditions for the Linear Non-homogeneous Moment Equations in Half-space
Ruo Li, Yichen Yang
We propose a necessary and sufficient condition for the well-posedness of the linear non-homogeneous Grad moment equations in half-space. The Grad moment system is based on Hermite…
A well-balanced moving mesh discontinuous Galerkin method for the Ripa model on triangular meshes
Weizhang Huang, Ruo Li, Jianxian Qiu +1
A well-balanced moving mesh discontinuous Galerkin (DG) method is proposed for the numerical solution of the Ripa model -- a generalization of the shallow water equations that acco…
Linear Moment Models to Approximate Knudsen Layers
Ruo Li, Yichen Yang
We propose a well-posed Maxwell-type boundary condition for the linear moment system in half-space. As a reduction of the Boltzmann equation, the moment equations are available to…
A general improvement in the WENO-Z-type schemes
Ruo Li, Wei Zhong
A new type of finite volume WENO schemes for hyperbolic problems was devised in [36] by introducing the order-preserving (OP) criterion. In this continuing work, we extend the OP c…
