Poisson

Solving Poisson Equation

Introduction When I started this blog I already expected to have projects that use the Fast Fourier Transform. I actually wrote down several topic ideas for the blog, both solving the Poisson equation and the subject this post will lead to were there, too. I already mentioned in the Relaxation Method post that one can … Read more

Lattice Boltzmann Density

Lattice Boltzmann

Introduction It’s time for an easier topic than the last time. I noticed – but I also expected it – that I have more success with projects like the Solar System than with a project like the Numerical Renormalization Group. There are mainly two reasons for it: it looks more spectacular to see a 3D … Read more

Event Driven Molecular Dynamics

Event Driven Molecular Dynamics

Introduction I intended to have some molecular dynamics code for this blog, something a little bit more complex than the one described at Newtonian Gravity post, perhaps something with neighbors lists or maybe again something about gravity but with a Barnes–Hut simulation. I’ll do that maybe later. I found that there are plenty of places … Read more
