Hello

I have made step-33 into a DG scheme for euler equations.

It uses the Trilinos AztecOO to solve the linear problems.

For steady state problems, it is recommended to use a block SSOR
preconditioner. This seems to correspond to the AZ_precond = AZ_sym_GS
option in aztec. Am I right ?

But if I use this option, I get an error that

"sym GS preconditioning can only be used with MSR matrices"

whereas I am using a Trilinos::SparseMatrix. What should I do to use SSOR in
deal.II ?

Thanks
praveen
