A mixed method for time-transient acoustic wave propagation in metamaterials
Jeonghun J. Lee
In this paper we develop a finite element method for acoustic wave propagation in Drude-type metamaterials. The governing equation is written as a symmetrizable hyperbolic system w…
Parameter robust preconditioning by congruence for multiple-network poroelasticity
Eleonora Piersanti, Jeonghun J. Lee, Travis Thompson +2
The mechanical behaviour of a poroelastic medium permeated by multiple interacting fluid networks can be described by a system of time-dependent partial differential equations know…
Analysis of hybridized discontinuous Galerkin methods without elliptic regularity assumptions
Jeonghun J. Lee
In this paper we present new stability and optimal error analyses of hybridized discontinuous Galerkin (HDG) methods which do not require elliptic regularity assumptions. To obtain…
A hybridized discontinuous Galerkin method for Poisson-type problems with sign-changing coefficients
Jeonghun J. Lee, Sander Rhebergen
In this paper, we present a hybridized discontinuous Galerkin (HDG) method for Poisson-type problems with sign-changing coefficients. We introduce a sign-changing stabilization par…
High order approximation of Hodge Laplace problems with local coderivatives on cubical meshes
Jeonghun J. Lee
In mixed finite element approximations of Hodge Laplace problems associated with the de Rham complex, the exterior derivative operators are computed exactly, so the spatial localit…
