1 Introduction

This page aims to explain how to install OpenFOAM+ on any Linux Distribution.

In the following chapters and sections is explained how to generally install OpenFOAM+ v1806+ and related dependencies, such as ParaView:

For dedicated instructions (complete and/or partial) for each Linux Distribution:

2 Installing from source code

The official instructions are made available here: OpenFOAM+ Installation From Source

A few details to keep in mind:

1. OpenFOAM+ (OpenFOAM plus) is a fork of the one distributed by the OpenFOAM Foundation. Do not assume that OpenFOAM and OpenFOAM+ are identical.
   • OpenFOAM+ is conceptually similar to the Fedora Project, in the sense that it provides new features that will mature over time and will be integrated into OpenFOAM once the new features are mature enough.
2. OpenFOAM+ v1806+ has several of the features of OpenFOAM 5 but not all, mostly because OpenFOAM+ was originally based on the development repository from the OpenFOAM Foundation, but features from the Foundation developments are handpicked and added to OpenFOAM+ as ESI-OpenCFD deems fitting. See the release notes for more details.
3. When in doubt about which GCC version to use, check the System Requirements page or the Installation/Compatibility Matrix page for information on compatible compilers (should be the same as OpenFOAM).
4. When it comes to ParaView, it's possible to avoid the need to build it from source code. If your Linux Distribution provides ParaView 3.12.0 or newer, you don't need to build ParaView from source code. Simply run:

   paraFoam -builtin

   and it will open the case in ParaView.
   • If the previous command worked, you can add the following alias command in your ~/.bashrc file:

       alias paraFoam='paraFoam -builtin'

   • In case you have an old Linux Distribution and still don't want to build ParaView from source code, get the latest binary version for Linux from ParaView's official website. Then add to your ~/.bashrc file the following line (adapt accordingly):

       export PATH=$HOME/Downloads/ParaView-4.2.0/bin:$PATH
