We performed cases of wave propagation on a case three-dimensional.

For that, we chose to simulate a copper crystal in CFC configuration with a mesh of size
3 6150 angstroems. For that we use the EAM potential with the file in the DYNAMO format found here. 

The sample is a cube of dimensions 300x600x144 angstroems cube.
The atomic zone is made of 1 024 000 atoms, which forms a cube with side of 300 angstroems.

Two finite elements zones  are respectively placed on top  and below the atomic zone (according to the Y axis). Consequently, boundary conditions are set periodic for zone finite elements and the atomic zone in the X and Z direction. The meshes used are both grids with 9 216 elements and 10 625 nodes.
