► Question-and-answer based CAPATCHA activated
  21 Mar, 2021
We have had problems recently with bots that automatically register thousands of spam users. Clearly our text-based CAPATCHA system, where a new user has to enter a few distorted characters from an image, has been broken. I have instead today activated a questions-and-answers based CAPATCHA system using a bunch of CFD-related questions that most CFD engineers should have no problems with.

If you have problems to answer one of these CAPATCHA questions please let me know. We should have questions that are difficult to answer for spammers, but easy to answer for anyone interested in CFD.

ESI OpenCFD Ltd. is pleased to announce the release of OpenFOAM-v2012.

The version released in December 2020 brings a lot of exciting new functionality and extension to the existing ones. Let us, among others, highlight a few:

In Meshing:
  • SnappyHexMesh - New thicknessModel allowing more precise y+ control in the first-cell layer

  • blockMesh - Improved write-vtk command-line option and simplified edge definition

In Numerics:
  • User selectable schemes for high aspect-ratio meshes
  • Lagrangian flow has improved particle tracking on moving meshes
  • MPPIC sub-models have been transferred to kinematic cloud to improve performance and allow interaction with moving meshes
  • Function1 allows setting of a period (more intuitive for slow oscilations)

In Solvers, Physics and Boundary Conditions:
  • New vibro-acoustics solver using finite area model to solve a thin vibrating shell
  • Improved turbulence treatment on the phase interface to reduce spurious velocities for interFoam and interIcoFoam
  • Viscosity models were generalized for easier implementation of new non-newtonian models

► OpenFOAM 8 Released
  22 Jul, 2020
OpenFOAM v8 Released - See Full Announcement

The OpenFOAM Foundation is pleased to announce the release of version 8 of the OpenFOAM open source CFD toolbox. Version 8 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 8 includes the following key developments.
  • Multiphase: selectable interpolation for interface-capturing, PLIC scheme.
  • Reacting multiphase: consolidated multiphaseEulerFoam solver and model development.
  • Transport: new MomentumTransportModels and ThermophysicalTransportModels libraries.
  • Thermophysical: thermodynamics and equation of state models, data input, refactoring.
  • Surface Film: huge performance improvements and better surface handling.
  • Heat transfer: better numerics and case setup, new thermal comfort modelling.
  • Particle tracking: renamed uncoupled solvers, improved tracking efficiency, injection.
  • Other models: transient/steady-state solvers, boundary conditions, reactions.
  • Mesh: improved snappyHexMesh and blockMesh, face centre calculation, cyclic patches.
  • Function Objects: improved visualization/field, residence time and configuration.
  • Case Configuration: new configuration/initialisation tools, coded Function1.
  • Computation: better data I/O, field caching, support for Arm processors.
  • Approximately 710 code commits, 200+ resolved issues
  • ISO/IEC 14882:2011 (C++11): tested for GCC v5.4+, Clang v3.8+, Intel ICC v18.0+.
OpenFOAM 8 is packaged for the following platforms, with ParaView 5.6.0 including Mesa with LLVM/Gallium acceleration for systems without a (supported) graphics card:
The OpenFOAM 8 Source Pack can be compiled on suitable Linux platforms.

Credits

OpenFOAM 8 was produced by:
  • Core Team (CFD Direct): Henry Weller (co-founder & lead developer); Chris Greenshields (co-founder), Will Bainbridge, Jakub Kníř

► blueCFD-Core 2020-1 has been released
  14 Apr, 2021
Yesterday we at FSD blueCAPE Lda have released blueCFD-Core 2020-1, which provides OpenFOAM 8 as a native build for Windows, with OpenFOAM binaries acting as normal Windows applications.

The installer for blueCFD-Core 2020-1 is installed separately from blueCFD-Core 2017, therefore both installations can coexist.

Released elements are:
The source code provided for the port of OpenFOAM 8 has been released here, as well as of ThirdParty-8 here.
As mentioned above, the development infrastructure is based on MSys2 and instructions for developing in a clean installation of MSys2 will be provided at openfoamwiki.net, as soon as possible.
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 developping blueCFD-Core 2020-1, are available there: milestone blueCFD-Core 2020-1.


Disclaimers:
  • FSD blueCAPE is responsible for the development and maintenance of the blueCFD®-Core project.
  • blueCFD® is a registered trade mark of FSD blueCAPE Lda.
  • FSD blueCAPE Lda 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.
  • blueCAPE Lda 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.

Addendum:
  1. We are very aware that we are already in the year 2021, given that in our numbering convention the version blueCFD-Core 2021 is reserved for OpenFOAM 9, which is estimated to be released sometime around June/July 2021.
  2. We will be publishing more information on how to sponsor the development of blueCFD-Core in the near future, in order to allow us to speed up developments and not be so far behind OpenFOAM Foundation's releases.
► Elmer-OpenFOAM library presentation on a webinar on April 1st
  31 Mar, 2021
Dear OpenFOAM users,

There is an webinar series on Elmer FEM in spring 2021. So far there has been general presentation by the Elmer team and now we are moving to contributed talks.

The next webinar will be given already tomorrow at 14 CET by Juris Vencels, the main developer of EOF library that enables Elmer and OpenFOAM to be linked efficiently via MPI. Good parallel scalability has been demonstrated by the library.

I thought this might be of interest for some OpenFOAM users who otherwise would not be bothered by finite elements. For magnetic field the Hcurl conforming basis functions offer some attractive features.

The webinar is free of charge. You can sign up for it here:

Best regards,
