[Trilinos-Users] Tpetra & block matrices (FEM)

[Cihan Altinay]

Great! Do you know what the state of the classes is in the latest 
release (12.4.2), i.e. is it worth for me to switch to using the block 
classes or should I rather wait? I don't mind if the interfaces change 
as long as they are functional.

Thanks again,
Cihan
