Installation and Running

Prerequisites

• Python 3.9+
• pip or uv package manager

Method 1: Using pip (Standard)

# Create virtual environment
python -m venv venv

# Activate virtual environment
# On Linux/macOS:
source venv/bin/activate
# On Windows:
venv\Scripts\activate

# Install dependencies
pip install -r requirements.txt

# Run the application
python main.py

Method 2: Using uv package manager

# Install uv (if not already installed)
curl -LsSf https://astral.sh/uv/install.sh | sh

# Run the application with uv
uv run nboms

Conclusions

This project demonstrates proficiency in:

• Computional Physics: Translation of mathematical models into executable code.
• Numerical Methods: Understanding of integration schemes, truncation errors, and stability considerations.
• Software Enginnering: Professional Python project structure with testing, documentation, and version control.
• Data Visualization: Interactive 3D plotting with Matplotlib, GUI development with Tkinter.
