Sequential matrix-free solver backend.
This can be used with a combination of {CGSolver, BiCGSTABSolver, MINRESSolver} as a solver and grid operator build from one of the following local operators:
Note: If you use BlockSORPreconditionerLocalOperator you need to use FastDGGridOperator!
GO | Grid operator implementing the matrix-free operator application |
PrecGO | Grid operator implementing matrix-free preconditioning |
