## Abstract An 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'Δ±ez (__Comput. Methods Appl. Mech. Engng__ 2009; **198**:1389β1400). In t
The computational e$ciency of "nite elements using Chebyshev basis functions is compared with that of standard equispaced lower order (bilinear and biquadratic) and higher order (bicubic and greater) pelements in the solution of the two-dimensional scalar wave equation when using explicit time integ
