An accurate and efficient local one-dimensional method for the 3D acoustic wave equation

Demonstratio Mathematica, 2022
We establish an accurate and efficient scheme with four-order accuracy for solving three-dimensional (3D) acoustic wave equation. First, the local one-dimensional method is used to transfer the 3D wave equation into three one-dimensional wave equations ...
