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
