► New COMSOL Forum on CFD Online
  19 Feb, 2023
By popular request from many users we have today opened a dedicated forum on CFD Online for the code COMSOL. The COMSOL forum can be found here:

https://www.cfd-online.com/Forums/comsol/

We have also moved all old COMSOL related threads to the new COMSOL forum. In the last years we have seen an increased traffic related to COMSOL and the new forum starts off with 290 old threads and 625 messages related to COMSOL.

I hope that the new COMSOL forum will become active and that it will make it easier for COMSOL users to discuss with each other.
► Some Data Lost, Server Restored From Backups
    4 Feb, 2023
The virtual server running cfd-online.com crashed during an OS update late Friday, Feb 3, 2023. In order to get cfd-online.com up and running again we were forced to restore a backup. The backup had been made very early on Friday.

Hence, most new additions to CFD Online, like new forum messages, new job-ads, new announcements and new events that were posted on Friday, Feb 3, 2023, have been lost.

If you posted something on Friday that is now gone please re-post it.

We are very sorry about this incident. I'm glad that we had a fairly recent backup so we did not loose a lot of data. Now I need some sleep...

► Users banned and posts deleted by mistake
  23 Sep, 2022
By mistake one of our moderators yesterday happened to ban about 5 legitimate users and deleted all of their posts. Fortunately it was possible to solve this quite quickly and I have now restored the deleted posts and removed the incorrect bans.

If someone is still missing their posts, or have been banned incorrectly from the forums, please let me know asap. You can send me a private message here on the forum or email to webmaster@cfd-online.com.

► OpenFOAM v10 Released
  12 Jul, 2022
OpenFOAM v10 Released - See Full Announcement

The OpenFOAM Foundation is pleased to announce the release of version 10 of the OpenFOAM open source CFD toolbox. Version 10 is a snapshot of the OpenFOAM development version which, through sustainable development, is always-releasable. It provides new functionality and major improvements to existing code, with strict demands on usability, robustness and extensibility.

OpenFOAM 10 includes the following key developments.
  • Multiphase: added models and improved performance / robustness of multiphase solvers.
  • Transport: properties consolidated into a single physicalProperties file.
  • Thermophysical: improved handling of conductivity and added documentation.
  • Heat transfer: improved thermal coupling in conjugate heat transfer.
  • Particle tracking: can now be plugged into any solver using the clouds fvModel.
  • Reactions: chemistry now solve for mass fractions to account for thermal expansion.
  • Parallelisation: new framework for load-balancing, decomposition and redistribution.
  • Mesh: general improvements to snappyHexMesh, blockMesh and other tools
  • Dynamic Mesh: non-conformal coupling (NCC) for rotating geometry, to replace AMI.
  • Dynamic Re-meshing: mesh-to-mesh mapping for mesh motion including engines.
  • Function Objects: more efficient output for sampling, and new field calculations.
  • Models and Constraints: now work for moving mesh cases and with function objects.
  • Boundary Conditions: new general conditions of pressure, velocity and temperature.
  • Case Configuration: created userTime to provide a customised measure of time.
  • Computation: improvements to distance-to-wall calculations, time handling and I/O.
  • Approximately 635 code commits, 161 resolved issues.
  • ISO/IEC 14882:2011 (C++14): tested for GCC v5.4+, Clang v10+ (v4+ should also work).
OpenFOAM 10 is packaged for the following platforms, with ParaView 5.6 including Mesa with LLVM/Gallium acceleration for systems without a (supported) graphics card:
The OpenFOAM 10 Source Pack can be compiled on suitable Linux platforms.

► preCICE Workshop 2023
  24 Jan, 2023
The 4th workshop of the open-source coupling library preCICE is around the corner: February 13-16, 2023, in Munich (limited places, registration closing soon).

This may be particularly interesting for people working on complex multi-physics simulations, such as fluid-structure interaction, conjugate heat transfer, and a wide range of other problems that need more than one simulation code (e.g., coupling OpenFOAM to your in-house code). The workshop includes training courses, talks, hands-on user support sessions, and a lot of interaction between participants.

Read more on https://precice.org/precice-workshop-2023.html

P.S.: While preCICE is not specific to OpenFOAM, most of the users seem to be interested in coupling some in-house or other open-source code to OpenFOAM, so I thought it would be fitting to post it in this category.
► CFD with OpenFOAM online training, training provided by Technical Courses 2023
  11 Jan, 2023
CFD with OpenFOAM course, 60 hours online, 10th February 2023, 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.
