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

[Alicia Klinvex]

Hello,

Tpetra still has block support in the Experimental namespace:
https://trilinos.org/docs/dev/packages/tpetra/doc/html/classTpetra_1_1Experimental_1_1BlockMultiVector.html

We are actively working on BlockCrsMatrix and BlockMultiVector; since they
are in the experimental namespace, they may change at any time.

Best wishes,
Alicia
