</div>Dune has interfaces to a range of FEM meshed, e.g. the alugrid which<br>
is a locally adaptive hexahedral mesh. In general you can interface<br>
any LA library you want. As part of Dune we develop dune-istl, a<br>
library for hierarchic matrices and iterative solvers. These matrices<br>
do also support complex and most of the solvers should work with<br>
complex values. There are only very few people using Dune with complex<br>
and a few bugs had to be fixed recently, but the idea is to have<br>
everything working with complex and the usual stuff does work.<br>
