An exact nonreflecting boundary condition was derived previously for timedependent elastic waves in three space dimensions [SIAM J. Appl. Math. 60, 803 (2000)]. It is local in time, nonlocal on the artificial boundary, and involves only first derivatives of the displacement. Here it is shown how to

A new calculation method is presented that allows the use of the acoustic characteristics of a given singularity as a boundary condition for a non-linear one-dimensional flow calculation. The method is based, on the one hand, on the non-linear decomposition of the pressure perturbation into forward
