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 moreSolving Poisson Equation

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 moreLattice Boltzmann

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 moreEvent Driven Molecular Dynamics

Newtonian Gravity

Introduction Newton is considered as being the one that started the modern physics, so something related with his work seems appropriate to start this blog. Besides, I had an old program simulating a solar system that I wrote quite a while ago. I wrote the program with the old OpenGL fixed pipeline and leapfrog integration, … Read moreNewtonian Gravity
