Abstract: Staircase approximation in the simulation of the arbitrarily irregular surface will cause artificial interference of wavefield. The body-fit coordinate transformation can accurately simulate ...
Abstract: The irregular surface topography has significant effects on seismic wave propagation, including introduction of free surface-related multiples, strong scattering, and distortion of the ...
This repository implements the discrete gyrator (a rotation in the phase space) on the 2D Hermite–Kravchuk (HK) basis via the SU(2) representation—using Wigner small‑d coefficients. It includes an n=2 ...
This repository contains the implementation of a Physics-Informed Neural Network (PINN)-Enhanced Finite Difference Method (FDM) for modeling energy balance in hydraulic fracture propagation. The ...
