template<class TSparseSpace, class TDenseSpace>
class Kratos::ResidualBasedBDFCustomScheme< TSparseSpace, TDenseSpace >

BDF integration scheme (for dynamic problems)

The second order Backward Differentiation Formula (BDF) method is a two step second order accurate method. This scheme is a generalization of the only displacement scheme, where any list of variables and its derivatives can be considered instead Look at the base class for more details
