This paper presents the release fv3 of the Complex Cellular Automata model Sciara for simulating lava flows. It is based on a Bingham-like rheology and both flow velocity and the physical time corresponding to a computational step have been made explicit. The model has been preliminary tested with satisfying results by considering the 2006 lava event at Mt Etna (Italy). A HTML5 based Web application with a WebGL 3D interactive visualization system has also been developed as user interface for Sciara-fv3. Eventually, the numerical code has been parallelised by the CUDA GPGPU paradigm, allowing for a considerable reduction of the execution time, despite the numerical code complexity

Abstract

This paper presents the release fv3 of the Complex Cellular Automata model Sciara for simulating lava flows. It is based on a Bingham-like rheology and both flow velocity and the physical time corresponding to a computational step have been made explicit. The model has been preliminary tested with satisfying results by considering the 2006 lava event at Mt Etna (Italy). A HTML5 based Web application with a WebGL 3D interactive visualization system has also been developed as user interface for Sciara-fv3. Eventually, the numerical code has been parallelised by the CUDA GPGPU paradigm, allowing for a considerable reduction of the execution time, despite the numerical code complexity
