PAR²

PAR² is a Lagrangian solute transport simulator using a parallelized Random Walk Particle Tracking (RWPT) method.

Getting Started

You can download the latest release of PAR² for Windows or Linux executable from here. Make sure your computer is equipped with an NVIDIA GPU and NVIDIA drivers are updated. You can control the simulation parameters through a YAML configuration file. Look inside the Examples folder to get started.

Build

The following software and libraries must be installed:

• cmake (version 3.8 or higher)
• CUDA Toolkit (tested with version 9.0)
• yaml-cpp library
• spdlog library (included in the source code)

Compile on Linux

1. Make sure to have a valid c++ compiler (e.g., gcc)

2. Create a build directory:

    mkdir Build  
    cd Build
   

3. Create makefile:

    cmake -DCMAKE_BUILD_TYPE=Release ..
   

4. Compile:

    make
   

Compile on Windows

1. Make sure to have Visual Studio 2017 installed

2. Create a build directory:

    mkdir Build  
    cd Build
   

3. Create MSVC solution:

    cmake -G "Visual Studio 15 2017 Win64" -T v140 -DCMAKE_BUILD_TYPE=Release -DYAML_ROOT=C:/path/to/yaml-cpp ..
   

4. Compile using the Developer Command Prompt for VS:

    devenv /Build Release par2.sln
