A program simulating behaviour of ideal gas particles.
Launch simulation.py file. An window asking for input data will appear:
Fill the fields and click Confirm. After a couple of seconds a simulation window should appear:
At the top, you can see three readings, updated live:
They stand for Time steps (number of iterations), Time passed (total approximate time elapsed in the simulation) and Pressure measured so far.
Have fun watching all the impacts!
For multiple tests, use an alternative file test_app.py. It is focused on high - performance and thus does not use any GUI. In command line you'll be asked for three inputs:
- Maximum starting velocity
- The value of (N / h)
- Depending on what you've chosen - Detector's heighth or number of atoms
Click enter and get the results! If you've chosen N as your variable, then you'll be presented 50 pairs of numbers standing for number of atoms in simulation (from 10 to 500, with a simulation step of 10) and measured pressure.
If you have chosen h as your variable, then you will be presented 41 pairs of numbers, standing for detector's level (from 0 to 40, with step of 1) and measured pressure.
Even using the test_app.py, the Python3 performance is limited. Some launches can take up to 50 minutes! Instead, I recommend using pypy3 (brew install pypy3). It's much faster than standard CPython (even the longest simulations will take up to 5 minutes), but has its own limits. There is a compatibility problem with pygame module, but fortunately - it's easy to solve. Go to ./utils/gui.py and ./utils/elements.py and comment out the second line:
# import pygame
Then type pypy3 test_app.py and enjoy your high-performance tests. Do not forget to uncomment when you want to use simulation.py because it wont't work!
