CP2K Tutorial

Introduction

This tutorial will guide you through the installation, configuration, and basic usage of CP2K. CP2K is a powerful quantum chemistry and molecular dynamics simulation package that supports various computational methods and simulation techniques.

Installation Steps

Windows

1. Download the Windows installer from the official website
2. Run the installer and follow the installation wizard
3. Add CP2K to your system PATH

Linux

1. Install required dependencies:

   sudo apt-get install cmake gcc g++ make python3-dev

2. Download and extract CP2K source code
3. Configure and compile:

   mkdir build
   cd build
   cmake .. -DCMAKE_BUILD_TYPE=Release
   make -j 4
   sudo make install

macOS

1. Install Homebrew if not already installed
2. Install CP2K using Homebrew:

   brew install cp2k

Basic Usage

Preparing Input Files

1. Prepare molecular structure file (XYZ format)
2. Create input file:
