PoissonSolver

This program solves the discrete poisson equation in the unit square in two dimensions.

INSTALLATION

1.) Download the source code

2.) Run the Makefile

RUN THE PROGRAM

1.) Execute ./poissonSolver program

2.) add three more command line arguments:

• m: the parameter which specifies h = 1/m (you observer N = m - 1 grid points in x and y direction respectively)
• x: the chosen algorithm (CG-Method, PCG-Method with incomplete LU decomposition, Jacobi-Method, Multigrid-Method)
• k: the chose function -> default: laplace(u) = -4 in Omega and u(x) = x^2 + y^2 in the bound of Omega
