Abstract
: Pulse propagation in elastic waveguides is simulated by means of finite volume methods. Results of calculations by means of the standard wave-propagation algorithm are compared with those obtained by the thermodynamically consistent excess quantities method. The main difference in these approaches is in the implementation of boundary conditions. The similarity and the distinction of the results are demonstrated.
