The Project

Introduction

The development of numerical models for simulating wave propagation in seismic regions has  tremendously evolved in the past ten years.

SPEED is a certified and rigorous numerical software for the reliable prediction of near-fault ground motions and seismic response of strategic structures in complex three-dimensional scenarios. SPEED can be employed to establish collapse-prevention strategies for strategic structures located in the proximity of a fault.

SPEED is based on the Discontinuous Galerkin Spectral Element method, a non-conforming domain decomposition technique combining the flexibility of discontinuous Galerkin finite elements with the accuracy of spectral techniques. SPEED naturally allows a non uniform polynomial degree distribution (p-adaptivity), as well as a locally varying mesh size (h-adaptivity). Such a built-in flexibility is mandatory in complex two and three dimensional problems featuring multi-scale phenomena.
