Estimation of the dispersion error in the numerical wave number of standard and stabilized finite element approximations of the Helmholtz equation (John Wiley & sons, 2011-06-10)
Open AccessAn estimator for the error in the wave number is presented in the context of finite element approximations of the Helmholtz equation. The proposed estimate is an extension of the ideas introduced in Steffens and D'iez ...
