► Email problems on forums - Forum registrations failed
  29 Jun, 2023
For the last couple of weeks we have had problems with outgoing emails from the forums on CFD Online. I hope that we have now solved the problems and that outgoing emails are now working again.

This means that everyone who registered on the forums from June 16 until today Jun 29 have not received any activation email to activate their forum account. This makes it impossible to activate your forum account.

You can ask for a new activation email to be sent to you using this form:

I apologize about the problems.

► OpenFOAM v11 Released
  11 Jul, 2023
OpenFOAM v11 Released - See Full Announcement

The OpenFOAM Foundation is pleased to announce the release of version 11 of the OpenFOAM open source CFD toolbox. Version 11 introduces modular solvers written as classes, in contrast to the traditional application solvers, integral to OpenFOAM since icoFoam in 1993. Modular solvers are simpler to maintain and extend, and are more flexible for multi-region simulations, e.g. conjugate heat transfer (CHT) with any type of flow, e.g. multiphase. Everything is backward-compatible, so: 1) application solvers will still compile in OpenFOAM; 2) launching an old application solver, e.g. simpleFoam, executes a script which runs the incompressibleFluid module on a single region.

OpenFOAM 11 includes the following highlights.
  • Modular Solvers: class-based solvers for greater flexibility, e.g. multi-region simulations.
  • Multiphase: vastly improved consistency and conservation in the multiphaseEuler module.
  • Transport: added anisotropic thermal conductivity.
  • Thermophysical: standardised the specification of property names in input file keywords.
  • Heat transfer: simplified critical boundary conditions for heat transfer between regions.
  • Particle tracking: generalised statistical distributions for size distributions in particles.
  • Liquids Films: full replacement which conserves mass and integrates to other models.
  • Meshes: redesign of dynamic mesh functionality and consolidated NCC.
  • Function Objects: improved field averaging and visualisation function objects.
  • Models and Constraints: numerous new models and constraints.
  • Boundary Conditions: consolidated mapped conditions and introduced MRF conditions.
  • Case Configuration: new foamToC application lists models and options in OpenFOAM.
  • Programming: new finite volume functions and improvements to algorithm sequences.
  • 964 code commits, 133 resolved issues.
  • ISO/IEC 14882:2011 (C++14): tested for GCC v5.5+, Clang v16+ (v10+ should also work).
OpenFOAM 11 is packaged for the following platforms, with ParaView 5.10.1 including Mesa with LLVM/Gallium acceleration for systems without a (supported) graphics card:
The OpenFOAM 11 Source Pack can be compiled on suitable Linux platforms.

► CFD with OpenFOAM online training, training provided by Technical Courses 2024
  14 Feb, 2024
CFD with OpenFOAM course, 60 hours online, 27th February 2024, price is 400€ - Euros.

Students will require approximately 60 hours to acquire a intermediate OpenFOAM level and obtain a certificate diploma. Nevertheless, additional material is provided for students who want to spend more than 60 hours and acquire a higher level.

The course is structured as follows:
- 11 theoretical chapters (each chapter includes a text and a videolesson)
- 8 basic exercises (each exercise includes a text and a videotutorial)
- 7 intermediate exercises (each exercise includes a text and a videotutorial).

The whole material (videolessons, exercises and texts) is available from the first day and there is no schedule. Videolessons are recorded. This enables each student to progress according to his learning pace.

Dear OpenFOAMers,

We are pleased to announce the 7th French/Belgian OpenFOAM users conference will be held in Paris-Saclay, France, on May 22nd and 23rd 2024.

You can already submit a presentation title here.
Early bird registration is open until February 28th 2024.

For this 7th edition, you will be able to choose between a workshop session OR a tour of the Synchrotron Soleil facility.
The workshop session will aim to gather users who want to share their knowledge and issues on specific topics (e.g. meshing, post-processing, ...).
Attendees will be asked to sort topics in order of preference beforehand in order to pick the most popular ones.

Important dates:
February 28th 2024: end of early bird registration

► November 2023 - Status Report for the blueCFD-Core project
  29 Nov, 2023
Greetings to all!

We have news on the current status of the blueCFD-Core project: http://bluecfd.github.io/Core/2023/11/29/status-report/

In a nutshell:
  1. We report there on the status of the project and how the funding we have received since 2022, has been invested. Quoting from there:
    Quote:

    As you can see here: commit history page for blueCFD-Core-dev branch, we have implemented a continuous integration bot named blueCFD-bot which automatically synchronizes our development branch with the OpenFOAM Foundation’s development line: OpenFOAM-dev commit history page
  2. The ongoing development has the objective to reduce the effort needed to make the release of each version of blueCFD-Core, which syncs up with each major release from the OpenFOAM Foundation. More details on how this is planned is given on that news post.
Do comment on the benefits this project has brought to you and reasons you see in it to continue moving forward!

For those who are not familiar with the blueCFD-Core project, it unleashes OpenFOAM at Windows, by bringing native builds on Windows of the releases and developments made by OpenFOAM Foundation, without the need to rely on any virtualization software nor Linux-based subsystem (e.g. WSL and Cygwin). It also enables you to build OpenFOAM-based custom code directly on Windows, without the need to cross-compile on Linux.

Best regards,
Bruno Santos

Instructors
Amirhossein Taran. Amirhossein is the instructor of "Coding OpenFOAM" on Faradars, the largest online training platform in Iran. As a researcher at Nexsys energy systems, his focus is Fluid-Solid Interaction in wind turbines. Apart from that, he has mastery over multiphase dispersed flows and spray atomization.

Ali Shayegh. During the past six years, Ali has been involved in holding three OpenFOAM workshops, and he is curious to go ahead with another one. As a cfd-online senior member, he helps learners to start from a blank text file and end up with flow calculations over a commercial airplane using OpenFOAM!
Ali’s research focus is the simulation of severe deformation in metal forming processes. Beside doing research at I-Form advanced manufacturing research center, he is currently the tutor of computational continuum mechanics at the University College Dublin, where students learn the basic use of Abaqus, Ansys Fluent, and OpenFOAM.
► OpenFOAM Research Software Engineering group
  29 Sep, 2023
After meeting at the OpenFOAM Workshop, myself and a few more people writing code that relies on OpenFOAM recently started a "Special Interests Group" to discuss anything related to software engineering practices in relation to OpenFOAM.


Short description from the webpage: "The RSE Special Interests Group aims to bring together developers of OpenFOAM and OpenFOAM-related projects. The main goal of the committee is to investigate software engineering practices that can facilitate the development of OpenFOAM and its integration with downstream and related projects, as well the FAIR (Findable, Accessible, Interoperable, and Reproducible) management of community-contributed research software and data. "


We have our second meeting today, 29/09/2023 at 13:00 CET (Germany), online, open to the public. Topic: "Reproducible code and cases, with examples from the OpenFOAM Journal".


Anyone can just join and leave at anytime, there is no registration required, or any commitment expected.



You can already vote for the next meeting date, and propose a topic here. We will be announcing some of the meetings here, but check the webpage for the latest information.
