class pymor.reductors.symplectic.QuadraticHamiltonianRBReductor(fom, RB=None)

Bases: pymor.core.base.BasicObject

Symplectic Galerkin projection of a QuadraticHamiltonianModel.

Parameters:

• fom – The full order QuadraticHamiltonianModel to reduce.

• RB – A SymplecticBasis prescribing the basis vectors.

Methods

class pymor.reductors.symplectic.ReducedQuadraticHamiltonianModel(T, initial_data, H_op, h=None, time_stepper=None, nt=None, num_values=None, output_functional=None, visualizer=None, name=None)

Bases: pymor.models.symplectic.BaseQuadraticHamiltonianModel

A general reduced quadratic Hamiltonian system.

In contrast to the QuadraticHamiltonianModel, the reduced model does not rely on a BlockVectorSpace as phase_space.
