Abstract: Since the precision of spatial derivative of wavefield calculated by staggered difference is superior to that by central difference, the formula of second-order staggered differential coefficient with 2N-order precision is constructed via mathematical deduction on… read more here.

Abstract: In this paper we propose a locally conservative, lowest-order staggered discontinuous Galerkin method for the coupled Stokes–Darcy problem on general quadrilateral and polygonal meshes. This model is composed of Stokes flow in the fluid region… read more here.

DOI: 10.1190/geo2017-0005.1
Abstract: ABSTRACTThe traditional high-order finite-difference (FD) methods approximate the spatial derivatives to arbitrary even-order accuracy, whereas the time discretization is still of second-order accuracy. Temporal high-order FD methods can improve the accuracy in time greatly. However,… read more here.
