The program poisson_solver3d.c
solves the 3D Poisson equation
The following algorithms are available:
- Jacobi,
- Gauß-Seidel,
- SOR (successive over-relaxation),
- CG (conjugate gradients).
All algorithms are parallelized with MPI using domain decomposition.
The MATLAB script plot_poisson.m
can be used to read the file result
and plot the result.
This program was written as an assignment during my Master's. I hope someone finds it useful.
