ICCG3: Subprograms for the solution of a linear symmetric matrix equation arising from A 7, 15, 19 or 27 point 3d discretization

Title of program: ICCG3 Catalogue Id: ACEX_v1_0 Nature of problem Elliptic and parabolic partial differential equations which arise in plasma physics applications (as well as in others) are solved in three dimensions. Plasma diffusion, equilibria, and phase space transport (Fokker-Planck equation) have been treated by similar methods in two dimensions using the codes ICCG2 and ILUCG2. These problems share the common feature of being stiff and requiring implicit solution techniques. Sometimes, the resulting matrix equations are symmetric; we solve them here wit ...
