Introduction

FALL3D is an Eulerian model for the transport and deposition of volcanic tephra developed at Barcelona Supercomputing Center in collaboration with the Geo-ELFS group at the INGV, Naples, Italy. The model solves the advection-diffusion-sedimentation equation using a finite difference explicit scheme. The main characteristics of the model are:
