# nbodies

Siple N Body simulation in Haskell (rendered using SDL2)

**Have fun ;)**

![Demo](docs/demo.gif)

## Setup and run

```bash

stack build

stack exec nbodies config/cfg.yml

```

## Configuration

The configuration is a Yaml file and has this structure:

```yaml

--- # Configuration

qtree: true                # display Quad Tree

barnesHut: true            # enable/disable Barnes Hut simulation

g: 1                       # universal gravitational constant

dT: 0.2                    # time interval of the simulation

scale: 1                   # simulation scale (0: auto)

bodies:                    # list of bodies

  - pos: {x:   0., y: 0.}  # position

    mass: 100.             # mass

    mom: {x:   0., y: 0.}  # momentum (speed)

```
