TUNAMI FF - CUDA Version 2011

TUNAMI (Tohoku University’s Numerical Analysis Model for Investigation of Far-field Tsunamis) FF - Version 2011 GPU based CUDA Code

Numerical simulation of far-field tsunamis using TUNAMI-FF (Tohoku University’s Numerical Analysis Model for Investigation of Far-field Tsunamis) was developed in the framework of NVIDIA CUDA kernels. The numerical model TUNAMI-FF is based on “tsunami numerical simulation with the staggered leap-frog scheme (Numerical code of TUNAMI-F1)” of Dr. Fumihiko Imamura, professor of tsunami engineering, school of civil engineering, Asian Inst. Tech. and Disaster Control Research Center, Tohoku University prepared in June, 1995 for TIME (Tsunami Inundation Modeling Exchange) project which was a joint effort of IUGG and IOC/UNESCO. In 1997, the TIME project manual was published by UNESCO as IOC Manuals and Guides No.35 “IUGG/IOC Time Project: Numerical method of tsunami simulation with the leap-frog scheme”.

TUNAMI-FF simulates all stages of a tsunami from the origin and the propagation in the ocean to the arrival at the coast and wave amplitudes at beach (~ 1 m water depth) by application of Green's law. It solves the linear shallow water equations on a structured regular grid with given resolution representing a coarse grid in the deep ocean. The implementation started in 2010 and many scientists contributed substantially.
