Solution of Poisson's equation using domain decoposition on a domain composed
of a rectangle and a semicircle with u=0 on the boundary.|
The problem is solved using domain decomposition.
Two variants are compared for solving the Schur-Complement system:
1. Dirichlet-Neumann method,
2. Neumann-Neumann method.
Starting with step 1 on a coarse triangulation, the system is
solved. After each step, the triangulation is refined, the system is
solved again until maxsteps is reached.
Usage: ddm(maxsteps, TOL)
INPUT: maxsteps: the maximum number of steps
TOL: tolerance for declaration of convergence
The OUTPUT includes a visualization of the grids, the solution, iteration
counts and error decay (compared to the FE-solution on the global domain).
