Elmer Discussion Forum

Hi all;
I am debating which Trilinos packages should be activated ( if any) for use with Elmer. Does this depend on what type of problem is being processed or is there a core set of packages that would be generally recommended for use with Elmer?

Hi

The main interest in Trilinos for us has been its multigrid library, ML. The Krylov method among different packages are not that much different, but the ML provides perhaps the best parallel multigrid preconditioner that can be coupled with Elmer. It is best suited for elliptic equations, both scalar and vector. For example, large scale elasticity equations might take good use of it.

Thanks. A succinct answer to my question.
