  • Local coderivatives and approximation of Hodge Laplace problems 
    Lee, Jeonghun; Winther, Ragnar (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)
    The standard mixed finite element approximations of Hodge Laplace problems associated with the de Rham complex are based on proper discrete subcomplexes. As a consequence, the exterior derivatives, which are local operators, ...
  • Parameter robust preconditioning by congruence for multiple-network poroelasticity 
    Piersanti, Eleonora; Lee, Jeonghun; Thompson, Travis; Mardal, Kent-Andre; Rognes, Marie (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    The mechanical behavior of a poroelastic medium permeated by multiple interacting fluid networks can be described by a system of time-dependent partial differential equations known as the multiple-network poroelasticity ...
  • Robust Error Analysis of Coupled Mixed Methods for Biot’s Consolidation Model 
    Lee, Jeonghun (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2016)
    We study the a priori error analysis of finite element methods for Biot’s consolidation model. We consider a formulation which has the stress tensor, the fluid flux, the solid displacement, and the pore pressure as unknowns. ...
