OpenFOAM Foundation

#OpenFOAM is the #CFD software owned and licensed free and #opensource only, by us — The OpenFOAM Foundation — managed and developed by CFD Direct.

The OpenFOAM Foundation has released #OpenFOAM v14, maintained and produced by @CFDdirect and funded by supporting organisations. The Foundation is sure that all its users would like to thank @CFDdirect
and the funders for their respective contributions. https://t.co/V1kWWjf9XX

In the initialisation of population balance cases, different types of size distribution can be specified, e.g. in different zones of the mesh in #OpenFOAM-dev https://t.co/Ir4dpa8zjZ

Improved efficiency of power functions with integer exponents in #OpenFOAM-dev https://t.co/KmZq7mkGVZ

In chemisty modelling, the high and low temperature limits are applied before the reaction rate evaluation in #OpenFOAM-dev https://t.co/XFnHSF9nc5

New solidDisplacement mesh mover calculates vertex motion from the interpolated displacement field of the solidDisplacement solver in #OpenFOAM-dev https://t.co/zo432XPqhq

Our Applied #CFD course extends the basic workflows and processes for running CFD with #OpenFOAM described in Essential CFD. We created the technology such as NCC and field-based Lagrangian so are best placed to teach it to users. https://t.co/mCqKYBKE9L

In the multiphaseEuler solver, blending can be applied to the interface compression coefficient in order to switch interface compression on or off in certain zones or in the presence of third phases, in #OpenFOAM-dev https://t.co/V99LWe19Jm

In the ODE solvers, the default tolerance can now be overridden with the "rowTol" parameter used to filter rows with a very small multiplier in #OpenFOAM-dev https://t.co/FeHDb52T4l

As we head towards the end of 2026, now is the time to apply for budget for #OpenFOAM #CFD Training in 2027. Check our web page about the courses we are providing in early 2027 https://t.co/0WfOJ9fE7c

[CFD Direct OpenFOAM @CFDdirect]

People ask which of our #OpenFOAM Training #CFD courses are best for them? The answer is "all of them" as demonstrated by the proportion of our training participants who return to complete all the courses we provide. https://t.co/kqjlyEpEBo

[CFD Direct OpenFOAM @CFDdirect]

Our #OpenFOAM Training is back in the classroom because people learn much more there. In person, you can easily ask "why" and, because we produce the code, you get a reliable answer. Unlike with an AI assistant, which doesn't know why. https://t.co/kqjlyEpEBo

[CFD Direct OpenFOAM @CFDdirect]

Internet searches and AI assistants can help users of #OpenFOAM. But they fail to explain the process of planning, building and running simulations and processing data that effective #CFD requires. Instead, our OpenFOAM Training teaches this process. https://t.co/kqjlyEpEBo

Our Essential #CFD course teaches the basic workflows and processes to configure and run CFD simulations with #OpenFOAM. We produce the code and designed the tools in OpenFOAM specifically for the workflows we teach in our training. https://t.co/47rHrJSGwi

Our Productive #CFD #OpenFOAM courses teaches the difficult skill of planning simulations making appropriate assumptions. It uses coded tools to extract diagnostic data to find mistakes and revise assumptions, essential for high quality CFD https://t.co/Ycna6cP4xd

For users of #OpenFOAM in the Americas, we provide our #CFD courses in Chicago. Classroom training is more interactive than online and includes more discussion and social interaction beyond the classroom https://t.co/1gOw9Vq4CR

In mesh-to-mesh mapping, new 'multiNearest' extrapolation avoids discontinuties between values when mapping introduces a new connection between regions of mesh in #OpenFOAM-dev https://t.co/DhkdNuhYbK

We have recently completed a major overhaul of our Programming #CFD course while updating it to #OpenFOAM v14. The course covers C++ and core OpenFOAM classes more deeply and our Updates page provides an overview of new content https://t.co/mGaXzVgm9V

Users of #OpenFOAM often don't know about the tools that can simplify their #CFD workflows and make them more robust. When people come on our OpenFOAM Training, they discover new tools and learn how to find more. https://t.co/kqjlyEpEBo
