Abstract.Refined method has been used for computing eigenvalues and the associated eigenvectors of large matrices. This paper studies the implementation of refined Davidson method on multi-core computer, and the method is used for parallel computing the natural frequencies of a plane wing and an aircraft pylon. The numerical experiments on multi-core computer show that the parallel refined Davidson method for computing eigenvalue problems is very effective.
