+
+Numerical Codes of Tsunami Simulation (CUDA-GPU) based on IUGG/IOC Time Project, IOC. Manuals and guides 35

+Numerical simulations of Far-filed tsunamis:
+
+Tohoku University’s Numerical Analysis Model for Investigation of Far-field Tsunamis – TUNAMI FF
+
+Assumptions:
+
+    The astronomical tides do not vary with respect to time throughout the tsunami simulation. The Still water Level in the computation is set equal to the water level at the beginning of the simulation
+    Both temporal and spatial grid lengths vary only at the ratio of 1:3:9 and so on, if the change of them is necessary
+    In the linear computation, no run up can be included, and therefore the computation is not carried out for the water depth shallower than 0.1 cm, and vertical walls are set in place of the actual slope.
+
+Numerical simulations of far-filed tsunamis, representing transoceanic propagation requires large area of computation. Such numerical simulations of far-filed tsunamis which travels more than 1000 km over ocean should be computed in polar-coordinates by considering earth as sphere of radius R, covered by the latitude and longitude (theta, lambda). Far-filed tsunami simulations covering wide areas of computation, in turn long travel distance may yield dispersion of wave components. Therefore in order to include physical dispersion term the equations of higher order approximation are used. But long travel time yields an inevitable accumulation of numerical error, for which the computation programme should be carefully designed.
+
+In the method of simulation, the linear long wave theory is expressed in latitude-longitude coordinates with different formulation of equations. When the liner theory is used, it is very easy to attain a high rate of vectorization in terms of programming. The current TUNAMI FF program for transoceanic propagation is composed to fully utilize the vectorizaion of parallel programming. The rate of vectorization of higher than 99% is a result of elimination of both the IF-sentences in DO-groups and the division operation.
