WaveRangeFollow @WaveRangeWaveRange 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.

2. | JAGURSFollow @JAGURSJAGURS 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. References: [1] Ando, K., M. Hyodo, T. Baba T. Hori, T. Kato, M. Watanabe, S. Ichikawa, H. Kitahara, H.
