sfepy.solvers.qeigen module¶
Quadratic eigenvalue problem solvers.
- class sfepy.solvers.qeigen.LQuadraticEVPSolver(conf, mtx_m=None, mtx_d=None, mtx_k=None, n_eigs=None, eigenvectors=None, status=None, context=None, **kwargs)[source]¶
Quadratic eigenvalue problem solver based on the problem linearization.
(w^2 M + w D + K) x = 0.
Kind: ‘eig.qevp’
For common configuration parameters, see
Solver.Specific configuration parameters:
- Parameters:
- method{‘companion’, ‘cholesky’} (default: ‘companion’)
The linearization method.
- solverdict (default: {‘kind’: ‘eig.scipy’, ‘method’: ‘eig’})
The configuration of an eigenvalue solver for the linearized problem (A - w B) x = 0.
- mode{‘normal’, ‘inverted’} (default: ‘normal’)
Solve either A - w B (normal), or B - 1/w A (inverted).
- debugbool (default: False)
If True, print debugging information.
