摘要:
In practical calculations it is often essential to truncate the computational domain by introducing artificial boundaries. The manner in which boundary conditions are approximated has an important influence on the accuracy of the results. In this paper we present a time domain technique to quantify the spurious reflection of waves from an artificial boundary, obtained by using a nonreflecting boundary condition based on rational approximations.
