Preconditioners for regularized saddle point problems with an application for heterogeneous Darcy flow problems
, based on coupled inner?outer iteration methods, are analyzed and applied to a Darcy not depend on this variation. Therefore, just two outer iterations can suffice. On the other hand, several iteratio...
