1.1 What is OpenFOAM?

OpenFOAM is an open source library designed for development of parallel or serial multi-dimensional modeling codes. OpenFOAM includes numerous C++ classes for finite volume, finite element, and Lagrangian particle tracking. OpenFOAM also comes with numerous computational fluid dynamics, combustion, and heat transfer programs that demonstrate the capabilities and usage of OpenFOAM. These solvers are useful for a wide range of scientific and engineering applications and can be customized as needed. Read more...

Nonetheless, if you are willing to be stubborn enough to spend countless hours delving into the World of Java, feel free to get the original source code for FoamX from the official OpenFOAM project at SourceForge.net:

  1. The last known version of FoamX is part of the main source code package: OpenFOAM-1.4.1.General.gtgz
  2. Download the file and then unpack it with the following command:
    tar -xzf OpenFOAM-1.4.1.General.gtgz
  3. The source code for FoamX is inside the folder: applications/utilities/preProcessing/FoamX
  4. Since building FoamX is part of the OpenFOAM build structure, then the last known instructions related to building FoamX are part of these instructions: Installation/Outdated/Howto compile OpenFOAM

Warning: Estimated amount of time necessary to get FoamX (barely) working with any of the latest OpenFOAM versions: 40 to 80 hours of dedicated work in coding in Java, depending on your level of experience.
