4 years ago What I tried:
141 paramList->set("Nullspace", m_inNullspace);
142 paramList->set("Coordinates", m_inCoords);
143 m_mueLuPreconditioner =
144 MueLu::CreateTpetraPreconditioner((RCP<Operator>)A, *paramList);But:
C++ exception with description "/ascldap/users/bmkelle/DeprecatedTpetra/Trilinos/packages/muelu/src/Interface/MueLu_ParameterListInterpreter_def.hpp:1798:

Question
@trilinos/muelu
The versions of MueLu::Create?PetraPreconditioner that take nullspace and/or coordinates as
RCP<MultiVector>arguments have been deprecated (#4868). If deprecated is off, and using the easy parameter list interface, what is the right way to set user nullspace? I've tried just setting them in the param list to theRCP<MultiVector>but I get an exception saying "Nullspace" isn't in the valid list. I'm trying to replace this code in shylu_dd/bddc/src/shylu_SolverMueLu.hpp:
