Abstract

This paper presents a simulation of a tsunami impact upon an urban coastline. Emphasis was given to the conservation of momentum, as its distribution in space and time is the main factor of the wave’s effects on the coastline. Due to this, a hybrid simulation method was adopted, based on the Smoothed Particle Hydrodynamics (SPH) method, enriched with geometric constraints and rigid body interactions. The implementation is the result of cooperation between the Bullet physics engine and our custom SPH engine, which successively process the dynamic state of the fluid at every timestep. Furthermore, in order to achieve better performance a custom data structure (LP grid) was developed for the optimization of locality in data storage and minimization of access time. Simulation data is exported to VTK files, allowing interactive processing and visualization. Experimental results demonstrate the benefits of impulse recording at potential hazard estimation and evaluation of defense strategies.
