Finite difference methods have become a cornerstone in the simulation of seismic wave propagation, providing a robust numerical framework to approximate the differential equations that govern seismic ...

The ODE subroutine returns the following values: optionally specifies the name of an IML module that is used to evaluate the Jacobian analytically. The Jacobian is the matrix J, with If the "jacobian" ...

Two-phase, incompressible flow in porous media is governed by a system of nonlinear partial differential equations. Convection physically dominates diffusion, and the object of this paper is to ...
