  • Reactions: improved robustness of numerics and chemistry and added general controls.
  • Mesh: refactored parts of snappyHexMesh, decomposition and manipulation tools.
  • Surface Film: introduced standard thermophysical modelling.
  • Function Objects: overhaul of packaged function objects for improved usability.
  • Models and Constraints: fvOptions replaced by more flexible fvModels and fvConstraints.
  • Case Configuration: enhanced scripts and added new Function2 functions of 2 variables.
  • Computation: improved robustness and performance of I/O, compilation, numerics.
  • Approximately 750 code commits, 200+ resolved issues.
  • ISO/IEC 14882:2011 (C++14): tested for GCC v5.4+, Clang v10+ (v4+ should also work).
OpenFOAM 9 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 9 Source Pack can be compiled on suitable Linux platforms.

► NUMAP-FOAM Summer School 2022, Sep 2022, Cambridge, United Kingdom
  11 May, 2022
Numerical Modelling of Coupled Problems in Applied Physics with OpenFOAM (NUMAP-FOAM)

Summer School 2022 at the University of Cambridge

Following the COVID-induced break, The Centre for Scientific Computing at the Department of Physics, The Cavendish Laboratory announces the 15th edition of the Summer School on Modelling of Coupled Problems in Applied Physics with OpenFOAM (NUMAP-FOAM) for graduate students and young researchers in Cambridge in September 2022. The Program Chair is dr. Hrvoje Jasak.


https://ccm.phy.cam.ac.uk/events/num...cambridge-2022

Description

The School aims to provide tuition at expert level for a small and selected group of students and researchers in academia and industry. The idea of the NUMAP-FOAM School is to expand the physical modelling knowledge, numerics and programming skills of attendees using OpenFOAM in their research through direct supervision and one-to-one project work. Lectures on chosen topics of mathematical and numerical modelling pertinent to coupled problems in engineering and applied physics will be delivered in addition. For further references, please contact the organisers or one of more than 150 alumni of previous editions of the School.

To ensure quality of work and individual supervision, the number of places is strictly limited.

Place and Time: New Venue

The Summer 2022 edition NUMAP-FOAM shall take place between Monday, 12 September 2022 and Friday, 23 September 2022, inclusive (10 working days). The School shall be held at the The Cavendish Laboratory, Department of Physics, (Maxwell Building), University of Cambridge, UK.

Topic Areas

Students are invited to propose their own topics for the School. Preference shall be given to project which require complex programming in OpenFOAM, advanced software design and implementation of complex and coupled physical models in OpenFOAM. Special topics for this year's Summer School include multi-phase and free surface flows, high-order discretisation methods (Discontinuous Galerkin), Reduced Order Modelling, Combustion modelling, Electro-chemistry in CFD and Magneto-hydro-dynamics applications.

How to Apply: NUMAP-FOAM Summer School 2022

To apply, please write a one-page description of the project you wish to work on, with current problems and goals to be achieved at the School. Application is open to all students on graduate University courses, as well as researchers in companies and government organisations with sufficient knowledge of OpenFOAM.

Please note this is NOT an introductory OpenFOAM course: significant understanding of the project and software is a pre-requisite for application.

Deadline for application is 15 June 2022. Successful candidates will be informed within two weeks of closing.

Accommodation and Costs

Attendees to the School should plan to cover their travel and accommodation expenses, ideally bringing a laptop computer with them. A registration fee for the School is GBP 2000 per attendee. It is recommended to look for accommodation at one of many Cambridge Colleges.

Contact Details

For further details and submission of project proposals, please contact dr. Hrvoje Jasak at hj348@cam.ac.uk.

► Support Drive 2022 for the blueCFD-Core project
  16 Mar, 2022
We are very happy to announce our 2022 Support Drive for the blueCFD-Core project, with clear objectives and how to achieve them.
With your contributions, we can maintain the blueCFD-Core project as a sustainable project, to streamline and automate most of the porting and building workflow, so we can stay in-sync with the developments by the OpenFOAM Foundation, make periodic releases, confirm the validity of each released build, as well as contribute to the whole community of OpenFOAM technology users and developers.

For more details on how you can contribute, please visit the dedicated page Funding for the blueCFD-Core project.

In line with our objectives for this project, this week we have sorted out several details on the documentation side of things, specifically:
  1. Moved the pages at Frequently Asked Questions to the category Q&A at the Discussions section, to make it simpler for us to maintain, as well as for the community to find and contribute to them.
  2. Created and/or moved over 40 reported issues to the various categories available at blueCFD-Core’s Discussions section:
    • Show and tell - to share common issues and how to work through them to solve them.
    • Q&A - namely Questions and Answers, for questions that are frequently asked.
    • Ideas - for people to share their ideas on what can be improved in blueCFD-Core.

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.
► CFD with OpenFOAM online training, training provided by Technical Courses 2022
    5 Mar, 2022
CFD with OpenFOAM course, 60 hours online, 18th March 2021, 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.

This equation establishes a linear relation between the interpoloted cells and the donor cells. Note that the coupling is only one way: The interpolated cells are influenced by the donor cells but not visa versa. The solution of the donor cells is achieved by standart finite volume discretization. The following code snipet shows how the overset interpolation is achived on matrix level:

Line 1,472: Line 1,472:
   
 
The above code starts with a loop over all interpolated cells.  The loop starts by retrieving the information required for the interpolation: f is 1 for an interpolated cells and 0 else, the weights w required for the interpolation, the indexes nbrs of the donor cells for each interpolated cells. The list stencilFaces_[celli] containts the position of the donor cells for the cell with the index celli in the extended upperAddr and lowerAddr array and stencilPatches_[celli] contains the id of the neighbor processor if the donor cell lays on a processor boundary.

The loop continous by setting the diagonal and the source to zero. Note that the diagonal will be set to one in the later stage of the loop since the sum of the weights is one.
  +
After that the coefficients of the matrix resulting from the overset interpolation are written. The lable facei determines the position in the lower and upper array very the coupling coefficients between donor and acceptor have to be stored. As fininal step the entries in the lower or upper array are written depending on which of the donor or acceptor cell lable is higher.
