WebThis leads to the objective of this work which is to develop a GPU implementation of LSRTM. In this work, the two-dimensional first-order acoustic wave equations are solved using the second-order finite difference on a staggered grid and a perfectly matched layer is used as an absorbing boundary condition. WebAbsorbing Boundary Conditions , by Robert Clayton and Bjorn Engquist Boundary conditions are derived for numerical wave simulation problems that minimize artificial …
