A METHOD FOR THE STABILITY ANALYSIS OF LOCAL ARTIFICIAL BOUNDARIES

  • Local artificial boundaries may induce numerical instability while being adopted in finite element or finite difference simulation of wave motion in infinite media. Starting from the step by step integral algorithm and considering the coupling between the motion of the boundarynodes and the internal nodes, the authors bring about a method which can give an approximate stability criterion of a local artificial boundary in numerical simulation of multi dimensional wave motion. The stability analysis of the...
