Using external direct solvers
+ +

+ Trilinos (via its Amesos package) can interface with a number of direct + solvers (see, for example, + this page for Trilinos 11.8). Most of them are external + packages to Trilinos and you will need to tell Trilinos configuration + scripts that you want to use them, for example via the + TrilinosWrappers::SolverDirect class. This can be tricky, + but adding defines similar to the following to the cmake command line + will achieve the goal: +
