There was a problem hiding this comment.
Does tpetra no longer store the sparsity pattern?

A first stab at using Tpetra to do the linear algebra inside of ASPECT. It compiles and it can run (some) models in serial, however there are still a lot of limitations and bugs.
Before this is finalized I will introduce a cmake variable to switch between Epetra/Tpetra depending on deal.II availability.
This currently requires a custom deal.II version with dealii/dealii#19403.
I mostly open this PR to track the progress with improvements in deal.II and to document the missing features that currently require changes to ASPECT in order to use Tpetra classes.
