Auxiliary variables for 3D multiscale simulations in heterogeneous porous media
Sandvin, Andreas; Keilegavlen, Eirik; Nordbotten, Jan Martin (Journal article, 2013-04-01)The multiscale control-volume methods for solving problems involving flow in porous media have gained much interest during the last decade. Recasting these methods in an algebraic framework allows one to consider them as ... -

Multiscale mass conservative domain decomposition preconditioners for elliptic problems on irregular grids
Sandvin, Andreas; Nordbotten, Jan Martin; Aavatsmark, Ivar (Peer reviewed; Journal article, 2011-06)Multiscale methods can in many cases be viewed as special types of domain decomposition preconditioners. The localisation approximations introduced within the multiscale framework are dependent upon both the heterogeneity ... -
Robust Multiscale Control-volume Methods for Reservoir Simulation

A unified multilevel framework of upscaling and domain decomposition
Sandvin, Andreas; Nordbotten, Jan Martin; Aavatsmark, Ivar (Conference lecture, 2010)We consider multiscale preconditioners for a class of mass-conservative domain-decomposition (MCDD) methods. For the application of reservoir simulation, we need to solve large linear systems, arising from finite-volume ...
