## Abstract Two iterative subspace methods (Arnoldi and JacobiβDavidson) are compared for solving typical quadratic eigenvalue problems arising when studying combustion instabilities. An academic, representative test case is presented with associated analytical solution. The efficiency of the itera

## Abstract In this paper the accuracy, efficiency and stability of two hybrid solvers are compared to FDTD in several complex scattering cases. The explicit hybrid solver, FDβFV, combines an unstructured FVTD solver with FDTD, and the explicitβimplicit solver, FDβFE, combines an unstructured FETD
A quasi-steady-state method is presented that integrates stiff differential equations arising from reaction kinetics. This predictor-corrector method is A-stable for linear equations and second-order accurate. The method is used for all species regardless of the time scales of the individual equatio
We present experiments with various solvers for large sparse generalized symmetric matrix eigenvalue problems. These problems occur in the computation of a few of the lowest frequencies of standing electromagnetic waves in resonant cavities with the finite element method. The solvers investigated ar
