OpenFOAM v2212 リリースノート

OpenCFD is pleased to announce the December 2022 release of OpenFOAM® v2212. This release extends OpenFOAM-v2206 features across many areas of the code. The new functionality represents development sponsored by OpenCFD's customers, internally funded developments, and integration of features and changes from the OpenFOAM community.

OpenFOAM is distributed by OpenCFD under the GPL License. In addition to source code packages suitable for compilation on a variety of Linux and other POSIX systems, this release also has a number of pre-compiled binary packages

• Ubuntu Linux: packaged installation for Ubuntu 22.04 (LTS), 20.04 (LTS), 18.04 (LTS), 22.10
• openSUSE Linux: packaged installation for Leap15.4, Leap15.3
• Redhat Linux variants: packaged installation for CentOS/Rocky 8, 7 and Fedora 37, 36, 35, ...

Windows users have three options for pre-compiled packages (more information):

• Using Windows Subsystem for Linux (based on Ubuntu, openSUSE etc.)
• Native executables with cross-compiled
• A docker installation

OpenFOAM apptainer support is provided via description files rather than pre-assembled images

• See packaging/containers

Mac OSX users have the option to compile from source, or use Docker containers for pre-compiled packages (more information).

v2212 User Upgrade Guide

Changes in behaviour

timeActivatedFileUpdate

For timeActivatedFileUpdate, missing files are now treated as a critical error (FatalIOError). These were previously treated as a simple error (FatalError), which downgrades to a Warning only when loading a functionObject and meant that configuration errors would not be noticed.

Spalart-Allmaras DES models

For SpalartAllmaras-based DES models, the previously-active ft2 term is deactivated by default. Its activation can now be managed using the new optional ft2 entry which is false by default.

Input Dictionaries

Force, Force coefficients

More consistent handling of priorities for binModels, forces. If the dictionaries are overspecified, give a coordinateSystem entry a higher prioriy than the CofR shortcuts.

Streamline Improvements

Some of the streamline handling has been further refined (eg, barycentric coordinates in interpolation instead of x/y/z). In the process the input requirements has been relaxed:

• default tracking direction is 'forward'
• The U (velocity) field doesn't need to be named in the sampled fields.

Improved handling of coordinateSystems

Wherever the coordinate system definition is embedded within a sub-dictionary scope the origin keyword is now optional. For example,

dict1
{
    coordinateSystem
    {
        origin (0 0 0);  // now optional here
        rotation ...;
    }
}

However, it remains mandatory if constructed without a sub-dict. For example,

dict2
{
    origin (0 0 0);   // still mandatory
    e1  (1 0 0);
    e3  (0 0 1);
}

With this change, the transform sub-dictionary can be written more naturally:

formatOptions
{
   vtk
   {
       scale 1000;  // m -> mm
       transform
       {
           rotationCentre  (1 0 0);
           rotation axisAngle;
           axis    (0 0 1);
           angle   -45;
       }
   }
}

Deprecated entries in histogram

The setFormat and formatOptions entries have been silently deprecated from the histogram function object.

Changes in utilities

Updated option names for transformPoints and surfaceTransformPoints

New options -auto-centre and -centre replace -auto-origin and -origin, respectively (old options still accepted as compatibility aliases). Changing to -centre avoids possible confusion in meaning with coordinate system origin().

effectivenessHeatExchangerSource

The effectivenessHeatExchangerSource fvOption has been renamed to heatExchangerSource. Its previous behaviour can be recovered by using the heatExchangerSource with the submodel of effectivenessTable.

histogram

The histogram function object has been refactored. Its previous behaviour can be recovered by using the histogram with the submodel of equalBinWidth. Also, output files per time-step are replaced with a single output file.
