Refined rayleigh-ritz
WebIn Rayleigh-Ritz method, we find that upon increasing the number of superimposed shape function terms, the result is refined even more, however, computation time increases exponentially as seen in the graph. But including more number of terms will not refine the results after a certain extent.

The Rayleigh–Ritz method is a direct numerical method of approximating eigenvalues, originated in the context of solving physical boundary value problems and named after Lord Rayleigh and Walther Ritz. The name Rayleigh–Ritz is being debated vs. the Ritz method after Walther Ritz, since the numerical procedure has been published by Walther Ritz in 1908-1909. According to, Lord Rayleigh wrote … WebHarmonic Rayleigh-Ritz extraction for the multiparameter eigenvalue problem. Bor Plestenjak. 2008, Electronic Transactions on Numerical Analysis.
