Member Function Documentation

◆ addGroupVariables()

template<typename T >

void ReferenceResidualInterface::addGroupVariables ( const std::set< T > & group_vars )

Add a set of variables that need to be grouped together.

For use in actions that create variables. This is templated for backwards compatibility to allow passing in std::string or NonlinearVariableName.

Template Parameters

T	string type used for variable names

Parameters

group_vars A set of solution variables that need to be grouped.

Definition at line 48 of file ReferenceResidualInterface.h.

  _group_variables.push_back(
      std::vector<NonlinearVariableName>(group_vars.begin(), group_vars.end()));
