◆ init()

void MAST::PKFlutterSolution::init ( const MAST::PKFlutterSolver &  solver,
const Real  k_red,
const Real  v_ref,
const Real  bref,
const RealMatrixX &  kmat,
const MAST::LAPACK_ZGGEV &  eig_sol 
)
virtual

initializes the flutter solution from an eigensolution

Definition at line 31 of file pk_flutter_solution.cpp.

◆ print()

void MAST::PKFlutterSolution::print ( std::ostream &  output)
virtual

prints the data and modes from this solution

Implements MAST::FlutterSolutionBase.

Definition at line 122 of file pk_flutter_solution.cpp.

◆ sort()

void MAST::PKFlutterSolution::sort ( const MAST::FlutterSolutionBase &  sol)
virtual

sort this root with respect to the given solution from a previous eigen solution.

This method relies on the modal participation. Flutter roots from previous and current solutions with highest dot product of modal participation vector are considered to be similar.

Implements MAST::FlutterSolutionBase.
