Alternating direction methods for parabolic equations in three space dimensions with mixed derivatives
Department of Mathematics, The University, Dundee, UK
An alternating direction implicit (ADI) method which requires the solution of three tridiagonal sets of equations at each time step is suggested for solving the general parabolic equation with variable coefficients in three space dimensions. A sufficient condition for stability is proved in the pure initial value case. Other existing finite difference schemes are mentioned and numerical results are presented.
