摘要/Abstract

摘要： In Refs. [2-4] there is an Adaptive Open Boundary Condition (AOBC) designed .for transient waves which overcomes the limitation of the existing Open Boundary Condition (OBC) and can be used for the cases of waves with arbitrary incident angles. In this article a new family of high or,der AOBC has been designed on the basis of the above mentioned AOBC with the first order. In comparison with all other OBC with the same order, this new family of AOBC has the highest precision.

关键词: semilinear wave equation, asymptotics, long time scale, application, adaptiveness, open boufidary condition, optimal precision
