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

== Input Dictionaries ==

=== Force, Force coefficients ===
More consistent handling of priorities for binModels, forces. If the dictionaries are overspecified, give a <code>coordinateSystem</code> entry a higher prioriy than the <code>CofR</code> 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 <code>U</code> (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 <code>origin</code> keyword is now optional. For example,
<code>dict1
{
coordinateSystem
{
origin (0 0 0); // now optional here
rotation ...;
}
}</code>
However, it remains mandatory if constructed without a sub-dict. For example,
<code>dict2
{
origin (0 0 0); // still mandatory
e1 (1 0 0);
e3 (0 0 1);
}</code>
With this change, the ''transform'' sub-dictionary can be written more naturally:
<code>formatOptions
{
vtk
{
scale 1000; // m -> mm
transform
{
rotationCentre (1 0 0);
rotation axisAngle;
axis (0 0 1);
angle -45;
}
}
}</code>

=== Deprecated entries in <code>histogram</code> ===
The <code>setFormat</code> and <code>formatOptions</code> entries have been silently deprecated from the <code>histogram</code> function object.

== Changes in utilities ==

=== Updated option names for <code>transformPoints</code> and <code>surfaceTransformPoints</code> ===
New options <code>-auto-centre</code> and <code>-centre</code> replace <code>-auto-origin</code> and <code>-origin</code>, respectively (old options still accepted as compatibility aliases). Changing to <code>-centre</code> avoids possible confusion in meaning with coordinate system <code>origin()</code>.

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

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