[Dune] Prospects of VariableBCRSMatrix

[Tobias Kasper Skovborg Ritschel]

It would certainly be nice not to undertake the task alone. I am fairly new to Dune.

I am, however, considering whether the MultiTypeBlockMatrix and the MultiTypeBlockVector data structures are sufficient for my application. Depending on how I structure my implementation, I might just have a 2x3 block matrix where each block is again a block matrix (i.e. each block of the 2x3 matrix is a BCRSMatrix<FieldMatrix< ... >>).

Do you have any experience with the MultiTypeBlock<Matrix/Vector> data structure?

I would like to have such feature too.

If you want, we can join forces on such a project. As Oliver mentioned, I suppose it's doable if one does not try to mimic BCRSMatrix's implementation too much, as Oliver already mentioned.

So, if you would like to work together on this feel free to contact me.

Best,
Lasse
