Foil 38 Discretization of Computational Formulation of 3D Wave Equation

From Numerical Formulation and Solution of Collision 0f two Black Holes CPSP713 Case studies in Computational Science -- Spring Semester 1996. by Geoffrey C. Fox
We take simple equally paced gridpoints in u, x, h, and z.
We have already seen for convection equation subtly in time discretization of this type of equation.
A stable explicit method can be obtained by a carefully chosen integral formulation described in Miller's memo.
This involves integrating over a box PQRS with sides parallel to the characteristic axes u=constant, v=constant
