CFD Direct OpenFOAM

You cannot learn #CFD with #OpenFOAM by Internet searches because they spew incorrect, outdated, biased advice, and context-free AI summaries. Instead, CFD Direct provides OpenFOAM Training with 5 courses spanning 11 days and 900 pages of manuals. cfd.tips/tr26

Removed the "Coeffs" suffix from the names of sub-dictionaries containing model coefficients, with backward compatibility in #OpenFOAM-dev github.com/OpenFOAM/OpenF…

The contents of an input file, with macros expanded, is now written to the terminal for debugging with a .#dump statement in #OpenFOAM-dev github.com/OpenFOAM/OpenF…

Multicomponent thermodynamic models can be specified in particle clouds, with functionality and syntax identical to that of Eulerian multicomponent thermoydnamic models in #OpenFOAM-dev github.com/OpenFOAM/OpenF…

From #OpenFOAM code architects, #Essential and #Applied #CFD Training #Virtual Europe, 22-25 Sep 2026. Discount packages available. Book now: cfd.tips/tveu

New "indentOrNl" token can be used to format text output cleanly in #OpenFOAM-dev github.com/OpenFOAM/OpenF…

See our training course catalogue for #OpenFOAM #CFD software, which spans 12 days (online) and 10 (in person); Available for public and on-site training delivery: cfd.direct/openfoam-train…

New "cell" zoneGenerator generates a cell zone from a face or point zone in #OpenFOAM-dev github.com/OpenFOAM/OpenF…

Learn from experts to write quality, C++ code in #OpenFOAM with our acclaimed #Programming #CFD course, #Cologne, Germany, 13-15 Oct 2026. Book your place now: cfd.tips/tcol

When executing foamPostProcess on a file containing a sequence of function objects, writing the output of intermediate fields can be deactivated with "writeControl none;" in #OpenFOAM-dev github.com/OpenFOAM/OpenF…

The new bXiQdot function object calculates and caches the heat release rate of the Weller b-Xi combustion model in #OpenFOAM-dev github.com/OpenFOAM/OpenF…

With the b-Xi combustion model, the reaction rate is now output by writing the bSource field with "cacheTemporaryObjects(bSource);" and "includeFunc writeObjects(bSource)" in #OpenFOAM-dev github.com/OpenFOAM/OpenF…

CFD Direct will provide a packed programme of talks, demos, discussions and training at The OpenFOAM Foundation Expo 2026. If you are a current, new or prospective user of Foundation #OpenFOAM, don't miss it. Book Chicago (Naperville) USA or London UK. openfoam.org/event/expo-2026

The original function1 field function has been renamed distanceFunction following the introduction of timeFunction in #OpenFOAM-dev github.com/OpenFOAM/OpenF…

New timeFunction field function specifies a time (only) varying condition, typically used with the functionalFixedValue boundary condition in #OpenFOAM-dev github.com/OpenFOAM/OpenF…

New surfaceRenamePatch utility renames a patch (region) of a surface geometry file in #OpenFOAM-dev github.com/OpenFOAM/OpenF…

The tangentialVelocity parameter can now be specified by a field function in the pressureInletOutletVelocity boundary condition in #OpenFOAM-dev github.com/OpenFOAM/OpenF…
