Linux For Open Source CFD
 |
Note. This linux image was build using SUSE Studio. This service will be shut down in February 2018, so this will be the last supported release until we transition to the new service (SUSE Studio Express). For more information, visit this link http://blog.susestudio.com/2017/11/shut-down-of-suse-studio-at.html.
If you are new to Linux, and you do not want to go thru the hustle and bustle of partitioning your hard drive, backing-up your data, and installing Linux and all the applications for CFD, CAD, meshing, and visualization, we highly recommend you to use this Linux version based on OpenSUSE 42.1 with KDE 4 desktop. You can install this Linux version under Windows, Linux and MacOS using any virtual machine application, but we highly recommend you to use vmware player (there is a free version for Windows).
This Linux version was created with CFD applications in mind for CFD users. It comes with many CFD, CAD, mesh generation, visualization, numerical libraries, optimization, plotting applications, and text editors pre-installed. It also comes with all the compilers and libraries necessary to compile most of the applications.
In this distribution, you will find the following CFD, CAD, optimization, solid modeling, visualization, and meshing applications pre-installed in the cfd user directory: OpenFOAM 5.x, Salome 8.2.0, Dakota 6.6, ParaView 5.1.2, GMSH 3.0.1, OpenVSP 3.8.1, Meshlab 1.3.3.
For those interested in Python, you will find a full installation of Anaconda Python distribution. Anaconda Python is a completely free enterprise-ready Python distribution for large-scale data processing, predictive analytics, and scientific computing.
Additionally, you will find many applications useful for algebra, matrix manipulation, numerical methods, plotting, scientific visualization, programming, debugging, mesh generation and manipulation, image manipulation, and geometry generation. Among others: blender, cgns, ddd, gnuplot, gnu parallel, kcachegrind, nemiver, openscad, R, valgrind, xflr5.
For text editing, you will find emacs, kwrite, gedit, leafpad, and vi. For office productivity, you will find a full installation of libreoffice.

OpenFOAM in Windows Subsystem for Linux (WSL)
If you are a Windows user, and new to Linux and OpenFOAM, and if you do not want to go thru the hustle and bustle of partitioning your hard drive, backing-up your data, and installing Linux and OpenFOAM, we highly recommend use Windows Subsystem for Linux (WSL).
The Windows Subsystem for Linux (WSL) is a feature of the Windows operating system that enables you to run a Linux file system, along with Linux command-line tools and GUI apps, directly on Windows, alongside your traditional Windows desktop and apps.
WSL requires fewer resources (CPU, memory, and storage) than a full virtual machine. WSL also allows you to run Linux command-line tools and apps alongside your Windows command-line, desktop and store apps, and to access your Windows files from within Linux. This enables you to use Windows apps and Linux command-line tools on the same set of files if you wish.
This WSL distribution is based on OpenSUSE 15.5 and comes with OpenFOAM 10, OpenFOAM 12, OpenFOAM v2406, paraview, and DAKOTA 6.20 pre-installed. It also comes with all the compilers and libraries necessary to compile most of the applications. The latest distribution is code named WSL-SUSEFoam2024v1.
To download the distribution in .vhdx format (compressed in .zip format, you will need to unzip it in order to install it). The .vhdx format only works using the latest version of WSL in Windows 11. The zipped archive is about 16.9 GB.
If you are using the latest version of WSL (Windows Subsystem for Linux), the maximum size of the virtual Linux distribution is 1TB. Have in mind that the size of the virtual hard drive can be expanded to any dimension, just follow these instructions.

OpenFOAM 9 in a Linux virtual machine
 |
If you are new to Linux and OpenFOAM, and if you do not want to go thru the hustle and bustle of partitioning your hard drive, backing-up your data, and installing Linux and OpenFOAM, we highly recommend you use this Linux virtual machine based on OpenSUSE 15.3.
You can install this Linux virtual machine under Windows, MacOS, and Linux (yes, you can install a Linux virtual machine in Linux). To do so, we highly recommend using VMWare Workstation player (for Windows or Linux), or VMware Fusion (for MacOS). Both versions are free for non-commercial personal use.
This virtual machine comes with OpenFOAM 9 and OpenFOAM v2106 pre-installed, plus a few additional applications for visualization, optimization, and data analysis. It also comes with all the compilers and libraries necessary to compile most of the applications.
At the following links, you can download the latest version (code named SUSEFoam2021v1) supporting OpenFOAM 9 and OpenFOAM v2106.
Note. The default hardware settings of the virtual machines are: 10 GB. RAM, 4 cores, and 8 GB. video memory. You can change these settings at any time.
User information:
User: cfd-user

If you are new to Linux and OpenFOAM, and if you do not want to go thru the hustle and bustle of partitioning your hard drive, backing-up your data, and installing Linux and OpenFOAM, we highly recommend you use this Linux virtual machine based on OpenSUSE 15.6.
You can install this Linux virtual machine under Windows, MacOS, and Linux (yes, you can install a Linux virtual machine in Linux). To do so, we highly recommend using VMWare Desktop Hypervisor solutions (for Windows, Linux, and Mac). VMware Desktop Hypervisor products Fusion and Workstation are free for non-commercial personal use.
This virtual machine comes with OpenFOAM 12 and OpenFOAM v2406 pre-installed, plus a few additional applications for visualization, optimization, and data analysis. It also comes with all the compilers and libraries necessary to compile most of the applications.
Note. The default hardware settings of the virtual machine are: 1000 GB storage (dynamically allocated), 16 GB RAM, 8 cores, and no 3D video hardware acceleration . You can change these settings at any time. You will need to extract the compressed virtual machine in the directory of your choice.
