A Measure for Eliminating Instability of the Multi-Transmitting Boundary
Abstract eng: The multi-transmitting boundary is a local artificial boundary used for numerical simulation of the near-field wave motion in infinite media. It has the advantages of clear physical conception, wide application and high precision. But like other local artificial boundaries, the multi-transmitting boundary encounters the instability of numerical simulation. One type of the numerical instabilities, the drift instability, is studied in this paper and results in a simple measure for eliminating this type of instability based on the combination of the multi-transmitting boundary with the viscous-spring boundary. Validity of the suggested measure is tested by numerical experiment of the anti-plane motion in wedge-shaped medium.
