Foil 28 Numerical Formulation of Three Dimensional Wave Equation in Polar Coordinates
From Master Foilset of Numerical Formulation and Solution of Collision 0f two Black Holes CPSP713 Case studies in Computational Science -- Spring Semester 1996. byGeoffrey C. Fox * Critical Information in IMAGE
The 3D Wave
Equation is:
We will study this as "essential issues" in wave extraction are exhibited
More generally take position and partial derivative dependent coefficients of second derivatives and add such forcing terms
Transform to Spherical
Polar Coordinates
Introduce characteristic
