We propose a finite element based discretization method in which the standard polynomial field is enriched within each element by a non-conforming field that is added to it. The …
The phase error, or the pollution effect in the finite element solution of wave propagation problems, is a well known phenomenon that must be confronted when solving problems in …

Recently, a discontinuous Galerkin method with plane wave basis functions and Lagrange multiplier degrees of freedom was proposed for the efficient solution of the Helmholtz …
The adjoint-weighted equation (AWE) formulation is applied to incompressible isotropic plane-stress elasticity for the solution of inverse problems. For the strong form of the problem …
