Fast Multipole Method

Posted on July 20, 2010 by moniker

To get a better intuition for how the Fast Multipole Method (FMM) approximates n-body interactions, I implemented the equations in Mathematica along with the exact solution. Below are some plots for different situations.  The thing to keep in mind is … Continue reading →

N-Body Problems

Posted on July 8, 2010 by moniker

N-Body problems inevitably come up when doing any most any kind of physical simulation work, particularly when particles are involved.  N-Body problems appear whenever the particles in a system construct a field that in turn determines their dynamics.  The classic … Continue reading →
