This paper suggests an expression of a residual-based a posteriori error estimation for a Galerkin ยฎnite element discretisation of the Helmholtz operator applied in acoustics. In the ยฎrst part, we summarise the ยฎnite element approach and the a priori estimates. The new residual estimator is then for
In part I of this investigation, we proved that the standard a posteriori estimates, based only on local computations, may severely underestimate the exact error for the classes of wave-numbers and the types of meshes employed in engineering analyses. We showed that this is due to the fact that the
