Code Quality CodeFactor


Source Code

  • Download and install Python3.x (>=3.6)
    • Select Add to PATH option
    • Select Install pip option
  • Download Version 0.7 or Latest Source
  • Run pip install -r requirements.txt or pip3 install -r requirements.txt (Need root access)
  • Run python3 install or python install (Need root access)


Easy Install

  • Run easy_install --upgrade gopem (Need root access)


  • Run docker pull ecsim/gopem (Need root access)
  • Configuration :
    • Ubuntu 16.04
    • Python 3.6

Exe Version (Only Windows)

⚠️ The portable build is slower to start

DMG Version (MacOS)

  • Download DMG-Version 0.7
  • Open DMG file
  • Copy GOPEM into your system
  • Run GOPEM

Exe Version Note

For GOPEM targeting Windows < 10, the user needs to take special care to include the Visual C++ run-time .dlls: Python >=3.5 uses Visual Studio 2015 run-time, which has been renamed into “Universal CRT“ and has become part of Windows 10. For Windows Vista through Windows 8.1 there are Windows update packages, which may or may not be installed in the target-system. So you have the following options:

  1. Use OPEM (Without GUI)
  2. Use Source Code
  3. Download and install Visual C++ Redistributable for Visual Studio 2015

System Requirements

GOPEM will likely run on a modern dual core PC. Typical configuration is:

  • Dual Core CPU (2.0 Ghz+)
  • 2GB of RAM

⚠️ Note that it may run on lower end equipment though good performance is not guaranteed.

Screenshot 2

  • Open CMD (Windows) or Terminal (UNIX)
  • Run python -m gopem or python3 -m gopem (or run GOPEM.exe)
  • Wait about 4-15 seconds (depends on your system specification)
  • Enter PEM cell parameters (or run standard test vectors)
  • For more information about parameters visit OPEM (Open Source PEM Fuel Cell Simulation Tool)
