What Should I learn in terms of concepts to do N-body simulations ? Is there any books that I can follow in this process ?
Thanks
Thanks
With a 2-body simulation...?Arman777 said:Hmm so where should I start ?
Yes that also came to my mind today. I ll start from there.berkeman said:With a 2-body simulation...?

Once I did a trajectory for an electron under the lorentz force. I guess this would be more complicated but I ll try.jedishrfu said:Finally, you need to understand the specifics of encoding a set of differential equations to solve for numerically in the environment chosen.
N-body simulations are used to model the dynamics of systems consisting of a large number of interacting particles, such as stars, galaxies, or molecules. They allow scientists to study the evolution and behavior of these complex systems over time.
To perform N-body simulations, one needs a strong foundation in mathematics and physics, particularly in mechanics and computational methods. Knowledge of programming languages and simulation software is also necessary.
The choice of simulation method depends on the specific system being studied and the desired level of accuracy and computational efficiency. Some common simulation methods include direct summation, Barnes-Hut tree algorithm, and Fast Multipole Method.
N-body simulations can be computationally intensive and require a significant amount of time and resources. Additionally, accurately modeling the initial conditions and accounting for all relevant forces and interactions can be challenging.
N-body simulations have a wide range of applications in astrophysics, cosmology, molecular dynamics, and other fields of physics. They are used to study the structure and formation of galaxies, the dynamics of star clusters, and the behavior of molecules in chemical reactions, among other things.
