WaveRange is a utility for compression of three-dimensional array output from computational physics solvers. It uses wavelet decomposition and subsequent range coding with quantization suitable for floating-point data.

JAGURS is a numerical code that computes tsunami propagation and inundation on the basis of the long waves, or the dispersive waves (Boussinesq-type). The code can take into account the effects of elastic deformation of the Earth caused by the weight of a tsunami and variations in seawater density in the vertical profile.
These are solved on a finite difference scheme using a staggered grid and the leapfrog method.
