Equilibration after EV: Improve performance of solver for patch-wise equation systems #4
Equilibartion following EV is based on patch-wise equation systems which have double-saddle-point-structure. For the imposition of the weak symmetry condition id turned out, that a Schur complement based solver improved the performance. This should also be tested and implemented for EV.
This issue is linked to the rework of the patch-wise data handling, in order to avoid the repeated recreation of the storage on each patch (see issue #5).
