A discontinuous finite element formulation for Helmholtz equation

A discontinuous finite element formulation for Helmholtz problems is presented with C0 continuity across inter-element boundaries enforced in a weak sense depending on two parameters β and λ whose choice is crucial for the performance of the proposed method. These parameters are chosen through one d...
