[dune-fem] Does anyone use fem::ISTLLinearOperator for rectangular matrices?

[Sacconi, Andrea]

Hi all,

is there anyone in dune-fem community successfully using and assembling a rectangular operator (for example, divergence of the velocity in Stokes, or any operator with domain and range with different dimensions), with Dune::Fem::ISTLLinearOperator as linear operator counterpart (instead of Dune::Fem::SparseRowLinearOperator)?

Cheers,
Andrea
