Consistent Velocity Approximation for Density Driven Flow and Transport
, 1998 The flow and transport problems that include the variation of the fluid density are much more difficult to solve numerically as the problems with constant density.

Least-Squares Mixed Finite Element Solution Of Variably Saturated Subsurface Flow Problems
, 1998 . A least-squares mixed finite element formulation is applied to the nonlinear elliptic problems arising in each time-step of an implicit Euler discretization for variably saturated flow problems. This approach simultaneously constructs approximations to

Version of Mixed Finite Element Methods for Parabolic Problems
, 1993 . We investigate a parabolic problem from the point of view of stability and approximation properties of increasing order mixed (in space) finite element methods. Previous estimates for the RaviartThomas projection are proven to be sharp.

Model order reduction preconditioning of parameterized Poisson equations
四川大学学报. 自然科学版This paper aims at the fast numerical solution of parameterized Poisson equation.A preconditioned conjugate gradient （PCG） method based on the model order reduction method is proposed to speed up the solution of the obtained discrete linear system.First，

A Particle-Partition Of Unity Method For The Solution Of Elliptic, Parabolic And Hyperbolic PDEs
. In this paper, we present a meshless discretization technique for instationary convection -diffusion problems. It is based on operator splitting, the method of characteristics and a generalized partition of unity method.

Mixed discontinuous Galerkin element for crustal rebound problem caused by glacier load
四川大学学报. 自然科学版With the intensification of global warming， continuous melting of overlying glaciers leads to crustal rebound and results in the development of collapse and landslide disasters in the periglacial area.These disasters can further transform into more ...
