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

► 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.
