In this article we describe extensive 3D simulations of elastic wave propagation in the bcc iron, which are based on the molecular dynamics methods. Basically it is about proper behavior testing of the MD simulations by the comparison of simulated stress waves velocities with the continuum theory. A behavior of the stress waves caused by surface and burried loading is described. In these simulations was used a N-body potential of Finnis-Sinclair type for the metals. The tasks of this type have a physical sense only if they are not devalued by the stress waves reflections from the free surfaces of the investigated sample. For this reason the models must be large enough and the simulations on these models can be realized only with the massive application of the parallel programming techniques.
