Threw this together to get more comfortable with Numpy.
|
|
Can simulate a few hundred bodies in 2 or 3 dimensions without much hassle.

|
|
Comments are non-existent, sorry about that.

|
|
To set up:
|
|
```shell
|
|
python -m venv venv
|
|
source venv/bin/activate
|
|
pip -r requirements.txt
|
|
```
|
|
|
|
To run:
|
|
```shell
|
|
# 2d simulation
|
|
./main.py -f 2d/simple.csv
|
|
|
|
# 3d simulation, increased gravity
|
|
./main.py -f 3d/some.csv -d 3 -g 30
|
|
```
|
|
|
|
To create a new start state:
|
|
```shell
|
|
# New 3d simulation of 100 particles in 300x200 box with max velocity components 2 and mass up to 3
|
|
./gen_data.py -c 100 -w 300 -h 200 -v 2 -m 3 > data/2d/new.csv
|
|
|
|
# New 3d simulation of 500 particles in 1000^3 box with velocity components up to 3 and mass up to 5
|
|
./gen_data.py -c 500 -d 1000 -w 1000 -h 1000 -v 3 -m 5 > data/3d/new.csv
|
|
```
