Hi Kubra, Someone asked a similar question just a few day ago, so I have some information pre-prepared for you.
LinearOperators do support Trilinos linear algebra classes, but there is no implementation for PETSc yet. The documentation is lacking a little bit in explaining how to use the parallelised version of LinearOperators, but I’d recorded this deficiency in this issue, along with a couple of examples. https://github.com/dealii/dealii/issues/12466 <https://github.com/dealii/dealii/issues/12466> The key points are 1. the use of the template parameter, e.g. linear_operator<TrilinosWrappers::MPI::Vector>(…), and, 2. the need for exemplars when wrapping preconditioners in LinearOperators. As for PETSc support, if this is something that you’d be interested in adding to the library, then we’d very much appreciate the contribution and would be happy to help you along the way.
