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
1 We take simple equally paced gridpoints in u, x, h, and z.
2 We have already seen for convection equation subtly in time discretization of this type of equation.
3 A stable explicit method can be obtained by a carefully chosen integral formulation described in Miller's memo.
4 This involves integrating over a box PQRS with sides parallel to the characteristic axes u=constant, v=constant
