3D EXAMPLES

The 3D version of PROSPERO is fully parallelized with the MPI interface. The code is written in standard C language and is intended to run on any Linux/Unix platform. Visualization of the results are provided with the Paraview software.

Aluminium Cube

A 28cm length cube of aluminium is excited by a source point on the left face at 0.5 MHz. Simulation is runned on a 350^3 grid points, corresponding to 9 points per wavelength for the S-wave and 18 points for the P-wave. Normal velocities are represented along the time.

 

Comparison with experimental measurements have been made with D. Brito (University of Pau, France). Normal displacements are measured with laser interferometry. Pressure seismograms realized on top and oposite faces are in good agrements (numeric: blue, experiments: green.
