► 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.


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.

► foam-extend-5.0 release
  20 Sep, 2022
Announcing foam-extend-5.0 Official Release

This is a major release of foam-extend-5.0 created from the nextRelease branch of foam-extend-4.1 which consolidates cumulative development since 14 October 2019. In total, the release consists of 5535 commits since the last release.
Pre-packaged binaries are produced for
- Ubuntu 20.04 LTS
- Ubuntu 22.04 LTS
- Ubuntu 18.04 LTS
Microsoft Windows compilation follows the Windows Power Shell Ubuntu sub-system.

Visit for more information.

Major new features:

* Physics modelling

* Proper Orthogonal Decomposition (POD) model development across a number of applications with tutorials and validation cases. POD uses the Method of Snapshots to create energy-consistent reduced order models which run 1000s of times faster than full CFD. POD analysis is also used to examine stability characteristics of flow regimes or to assemble "digital twin"-type models. POD has been deployed across a number of applications, with new tutorials.

* Extension to porous zone models for thermal modelling and heat transfer, including implicit coupled conjugate heat transfer

* Physics modelling updates for coal combustion

* Handling of derived forms of enthalpy in thermophysical models with correct boundary condition setup (coupled interfaces)

* Numerics

* Immersed Boundary (Surface) method: major improvements. Consistency errors in parallel cutting and interaction with coupled boundaries have been resolved. Further type-consistent boundary conditions on IB surfaces have been adeed, with correct mapping and post-processing. Major robustness improvements in the method. Algorithmic improvements in immersed boundary handling; cutting, dead cells, extended sets of boundary conditions. Rewrite of cut cell handling, parallelism and consistency updates.

* Immersed boundary with interfering patches: multiple intersections

* Updated algorithms for buoyant flows: correct limit of incompressibility and consistent handling of stratified flows. Solvers represent incompressible results for canonical flows without instability

* Consistency updates for Multiple Rotating Frames (MRF) of reference, with accurate geometry handling. Consistent and convergent integration with block pressure-velocity solvers

* Algorithmic updates for steady compressible turbomachinery flows. New implementation of rothalpy handling with better consistency in rothalpy jump coupled boundary conditions

* Use of block-AMG solvers for block-coupled p-U solvers: see tutorials

* Updated handling of bounded flux boundary conditions

* New 01 bounded convection schemes

* Better reporting of flux check

* Updated algorithms for partial overlap GGI interface pairs

* Change in handling of adjustPhi for moving deforming meshes

* HPC and parallelism, performance improvements

* Major improvement in handling of processor boundaries and other cached coupled interface patch types. This resolves long-standing bugs in FOAM-OpenFOAM development lines and results in significant reduction in number of iterations of linear solvers. Further, numerous stability and consistency problems in parallel execution have been resolved

* Improvements for large memory usage in large-scale HPC cases

* Incremental consistency work on block-coupled solvers for incompressible flows

* Incremental improvement in performance for parallel Oveset Mesh capability. Update in low-level communication and consistency

* Clean-up of boundary condition updates in absence of database field access

* Dynamic Mesh

* Full deployment of dynamic load balancing with AMR or other dynamic mesh features at the level of topoChangerDynamicFvMesh

* Refactoring of dynamic mesh solvers with algoritmic efficiency improvements

* Changes in dynamic mesh handling: efficient and consistent geometry updates

Software engineering

* Port to gcc-9 and gcc-11
* c++-11 updates: default destructors, delete automatically generated
* update of the build system using native third party packages whenever possible
* Change in style to FatalErrorInFunction sytnax
* new VectorN types for extended coupling in block matrices

Happy FOAM-ing,

I am a graduate student majored in energy and thermal engineering and currently studying flame behaviours under extreme conditions in mesoscale combustors, simulations and numerical approches are needed to gain supplemental data for experiments in quantitative analysis. OpenFOAM provides a wide and diverse variety of tools for the realization of user-defined functions, hence is perferable to commercial CFD softwares.
