Something broke during a live-cloning of the virtual server running CFD Online on Sunday night. I am not sure what happened.The site has been down during a large part of Sunday.

I was able to start the cloned virtual server on a backup server though. The CFD Online site is now up and running again, but on a backup server. I hope no data was lost, but if you miss something that you posted during Sunday it might be due to this.

I will try to live-clone the virtual server running CFD Online back to the production server and start it there again. The production server is a bit faster.

OpenFOAM v11 Released - See Full Announcement

The OpenFOAM Foundation is pleased to announce the release of version 12 of the OpenFOAM open source CFD toolbox. Version 12 takes advantage of modular solvers and non-conformal coupling (NCC) to improve simulations with multiple regions, including simplifying meshing and coupling. Work has continued on the rewrite of particle code, e.g. injection and distribution, parallel decomposition, redistribution and load balancing. There are some new, useful boundary conditions and the option to include units, e.g. [bar], with input values, which are converted accordingly. The installation of third party software is easier, with the openfoam12 package for Ubuntu 24.04 & 22.04 now using the standard paraview package.
OpenFOAM 12 includes the following highlights.

• Modular Solvers: support source terms for one variable for equations of other variables.
• Multiphase: improved models for mass, momentum and heat transfer, and solid phases.
• Turbulence Modelling: robust limiting of fields simplified and corrected wall functions.
• Heat: added viscous heating model and improved naming in thermodynamic properties.
• Particle Tracking: generalised injection and particle distributions.
• Meshes: upgraded mesh generation and coupling of multiple mesh regions.
• Parallel Running: efficient options for load-balancing, decomposition and redistribution.
• Function Objects: moved to a system/functions file, and added new function objects.
• Models: added volume and mass sources which are added to mass continuity.
• Boundary Conditions: new pressure, velocity and temperature boundary conditions.
• Case Configuration: parameters can include units, e.g. [bar].
• Programming: foamFind script to search source code; example coded function objects.
• Other: Easier installation of ParaView and decomposition libraries.
• 722 code commits, 100+ resolved issues.
• ISO/IEC 14882:2011 (C++14): tested for GCC v5.5+, Clang v16+ (v10+ should also work).

OpenFOAM 12 is packaged for the following platforms:

• Ubuntu Linux: packaged installation for Ubuntu 20.04, 22.04 and 24.04;
• Windows: installation using Windows Subsystem for Linux with Ubuntu packs;
• macOS: installation using Canonical Multipass with Ubuntu packs.

The OpenFOAM 12 Source Pack can be compiled on suitable Linux platforms.

OpenFOAM 12 was produced by:

• Maintainers (CFD Direct): Henry Weller, Will Bainbridge, Chris Greenshields.
• Contributors: Timo Niemi, Juho Peltola, Heikki Kahila, Bulut Tekgül, Stanislau Stasheuski.

Licence

Today we at FS Dynamics Portugal have released blueCFD-Core 2024-1, which provides OpenFOAM 12 as a native build for Windows, with OpenFOAM binaries acting as normal Windows applications.
This was possible thanks to our various sponsors, benefactors and donators!

The installer for blueCFD-Core 2024-1 is installed separately from older blueCFD-Core versions, therefore these installations can coexist.

Released elements are:

• blueCFD-Core-2024-1-win64-setup.exe
  • blueCFD-Core 2024-1 provides MSYS2, OpenFOAM 12 and ParaView 5.11.2.
  • 1173 MiB installer, SHA1: 87a16cd49ba891c9a5ff24d6c24b832e44f6cee7
• The Release Notes for blueCFD-Core 2024-1 page has been created for this release.
• The Funding page has been updated, to reflect the funding the project has received so far, as well as the work done so far.
• The Project Management page is public, allowing people to know how things are coming along and what are the upcoming objectives for 2024 and 2025.
• A wiki is available for software developers and system installers: blueCFD-Core wiki

The source code provided for the port of OpenFOAM 12 has been released here, as well as of ThirdParty-12 here.
As mentioned above, the development infrastructure is based on MSYS2. As listed in the Funding page page, one of our objectives is to provide updates and builds of OpenFOAM via MSYS2 package manager, however this is not yet available with this release. That said, instructions are available on blueCFD-Core’s wiki on:

1. Preparing a new MSYS2 installation for blueCFD‐Core development
2. Quick notes on how to update build
3. Loose notes on building custom code

For a complete list of bug reports, issues and wishes that have been submitted to the blueCFD-Core project, see the Issue Tracker page. For example, a complete list of issues and tasks that were conducted for developing blueCFD-Core 2024-1, are available there: milestone blueCFD-Core 2024-1.


Disclaimers:

• FS Dynamics Portugal is responsible for the development and maintenance of the blueCFD®-Core project.
• blueCFD® is a registered trade mark of FS Dynamics Portugal.
• FS Dynamics Portugal is an FS Dynamics company.
• This offering is not approved or endorsed by OpenCFD Limited, producer and distributor of the OpenFOAM software via www.openfoam.com and owner of the OPENFOAM® and OpenCFD® trade marks.
• FS Dynamics Portugal is a contributor to the OpenFOAM Foundation, but the majority of the specific modifications needed in the source code for running OpenFOAM natively on Windows, will not be accepted in the official releases of OpenFOAM by the OpenFOAM Foundation, mostly due to the maintenance overhead associated to supporting closed-source operating systems.

Dear all,

It is our great pleasure to announce the next FOAM@Iberia Users Meeting, to be held in the University of A Coruña (Ferrol, Spain) on the 3rd and 4th of October, 2024.

All OpenFOAM users, whether beginners or advanced, are welcome to participate and share knowledge, ideas, and experiences in a friendly and collaborative environment. Don't miss out on the chance to learn and network with FOAMers from the Iberian peninsula!

You can still send your contributions until the 25th of July 2024, and registration is currently open.
