in the bin/ directory of the OpenFOAM installation. If no problems are
reported, proceed to "3. Installation"; otherwise contact your system
administrator.

<div id="text-2.1">
<p>The ParaView 3.3 visualisation package requires that Qt version 4.3.x MUST
be installed on the system. Earlier or more recent versions (4.2.x or
4.4.x) will NOT work. To check whether Qt4 is installed, and the version,
type:
</p><ul>
<li>
qmake --version
</li>
</ul>
<p>The ParaView binary executables in the ThirdParty distribution will only
work with PRECISELY the same version of Qt with which it was compiled. The
64-bit version of ParaView was compiled with Qt-4.3.1 (with openSuSE-10.3)
and the 32-bit version of ParaView was compiled with Qt-4.3.2 (with
ubuntu-7.10). If the user finds that a ParaView binary fails to run, then
it is almost certainly due to a conflict in compiled and installed Qt
versions and they will need to consult the section below on "Compiling
ParaView and the PV3FoamReader module."
</p>
<p>
The default versions of Qt used by some GNU/Linux releases are as follows.
</p><ul>
<li>
ubuntu-7.10: Version 4.3.2
</li>
<li>
ubuntu-8.04: Version 4.3.4
</li>
<li>
openSuSE-10.2: Version 4.2.1 - too old
</li>
<li>
openSuSE-10.3: Version 4.3.1
</li>
<li>
openSuSE-11.0: Version 4.4.0 - too new
</li>
</ul>
<p>For openSuSE 10.2, 10.3 and 11.0, Qt version 4.3.5 can be downloaded from:
<a href="http://download.opensuse.org/repositories/KDE:/Qt43">http://download.opensuse.org/repositories/KDE:/Qt43</a>
</p>
<p>
Compilation and running of ParaView has been successful using the libraries
downloaded in the "libqt4-dev" package on ubuntu.

<p>
The environment variable settings are contained in files in an etc/ directory
in the OpenFOAM release. e.g. in
</p>
<ul>
<li>
$HOME/OpenFOAM/OpenFOAM-&lt;VERSION&gt;/etc/
</li>
<li>
where &lt;VERSION&gt; corresponds to the version 1.4, 1.5, &hellip;
</li>
<li>
EITHER, if running bash or ksh (if in doubt type 'echo $SHELL'), source the
etc/bashrc file by adding the following line to the end of your
$HOME/.bashrc file:
<ul>
<li>
. $HOME/OpenFOAM/OpenFOAM-&lt;VERSION&gt;/etc/bashrc

<p>OpenFOAM may also be installed in alternative locations. However, the
installation directory should be network available (e.g., NFS) if parallel
calculations are planned.
</p>
<p>
The environment variable 'FOAM_INST_DIR' can be used to find and source the
appropriate resource file. Here is a bash/ksh/sh example:

<h2 id="sec-4">4 Building from Sources (Optional)</h2>
<div id="text-4">
<p>If you cannot find an appropriate binary pack for your platform, you can build
the complete OpenFOAM from the source-pack. You will first need to compile or
obtain a recent version of gcc (we recomend gcc-4.3.?) for your platform,
which may be obtained from <a href="http://gcc.gnu.org/">http://gcc.gnu.org/</a>.
</p>
<p>
Install the compiler in
$WM_PROJECT_INST_DIR/ThirdParty/gcc-&lt;GCC_VERSION&gt;/platforms/$WM_ARCH$WM_COMPILER_ARCH/
and change the gcc version number in $WM_PROJECT_DIR/etc/settings.sh and
$WM_PROJECT_DIR/etc/settings.csh appropriately and finally update the
environment variables as in section 3.
</p>
<p>
Now go to the top-level source directory $WM_PROJECT_DIR and execute the
top-level build script './Allwmake'. In principle this will build everything,
but if problems occur with the build order it may be necessary to update the
environment variables and re-execute 'Allwmake'. If you experience
difficulties with building the source-pack, or your platform is not currently
supported, please contact &lt;enquiries@wikki.co.uk&gt; to negotiate a support
contract and we will do the port and maintain it for future releases.

#+TITLE: *OpenFOAM release notes for version 1.5*
#+AUTHOR: Hrvoje Jasak.
#+DATE: 19 August 2008
#+LINK: http://www.wikki.co.uk
#+OPTIONS: author:nil
* Overview
OpenFOAM-1.5 is is a significant upgrade to version 1.4 in ways which are
outlined below. This release passes all our standard tests and the tutorials
have been broadly checked. If there are any bugs, please report them using
the instructions set out in: http://www.openfoam.org/bugs.html.
Most of the developments for this release are in: new applications, e.g. for
multiphase flow and cavitation, buoyancy-flow and heat transfer, high speed
flows and even molecular dynamics; new utilities, e.g. for meshing and case
monitoring; and, new modelling, e.g. in Lagrangian particle tracking,
radiation and rotating frames of reference. With these new applications come
numerous new example cases.
* GNU/Linux version
The 64bit binary packs of the OpenFOAM release were compiled on a machine
running SuSE GNU/Linux version 10.3 and the 32bit on a machine running Ubuntu
GNU/Linux version 7.1 and also tested on Ubuntu 8.04. We recommend that
users run OpenFOAM on one of these or a similar recent version of GNU/Linux.
This release has also been successfully compiled and tested on older GNU/Linux
releases but this requires the installation of Qt 4.3.? for ParaView-3 to run.
* C++ Compiler version
+ Released compiled with GCC 4.3.1, the latest version.
+ Built in support for the Intel C++ 10.? compiler (untested).
+ The choice of the compiler is controlled by the setting of the $WM\_COMPILER
and $WM\_COMPILER\_ARCH environment variables in the OpenFOAM-1.5/etc/bashrc
(or cshrc) file.
+ The location of the installation of the compiler is controlled by the
$WM\_COMPILER\_INST environment variable in the OpenFOAM-1.5/etc/settings.sh
(or settings.csh) file.
* Developments to solvers (applications)
+ New rhoCentralFoam solver for high-speed, viscous, compressible flows using
non-oscillatory, central-upwind schemes.
+ New interDyMFoam solver for 2 incompressible, isothermal, immiscible fluids
using a VoF phase-fraction based interface capturing approach, with optional
mesh motion and mesh topology changes including adaptive mesh
(un)refinement. Useful for simulations such as tank filling, sloshing ---
using solid body motion e.g. SDA or SKA (6DoF) --- and slamming (using the
mesh motion solver) and other large-scale applications that benefit from the
efficiency gain of adaptive mesh (un)refinement of the interface.
+ New compressibleInterFoam solver for 2 compressible, isothermal, immiscible
fluids using a volume of fluid (VoF) phase-fraction approach for
interface-capturing. The momentum and other fluid properties are of the
"mixture" and a single momentum equation is solved. Turbulence is modelled
using a run-time selectable incompressible LES model.
+ New interPhaseChangeFoam solver for 2 incompressible, isothermal, immiscible
fluids with phase-change, e.g. cavitation. Uses VoF interface capturing,
with momentum and other fluid properties described for the ``mixture'' and a
single momentum equation is solved. The set of phase-change models provided
are designed to simulate cavitation but other mechanisms of phase-change are
supported within this solver framework.
+ New rasCavitatingFoam solver for transient cavitation using a barotropic
compressibility model, with RAS turbulence.
+ New lesCavitatingFoam solver for transient cavitation using a barotropic
compressibility model, with LES turbulence.
+ New chtMultiRegionFoam solver that couples conjugate heat transfer in a
solid to a buoyancy-driven flow simulation.
+ New PDRFoam solver for compressible premixed/partially-premixed turbulent
combustion that includes porosity/distributed resistance (PDR) modelling to
handle regions containing solid blockages which cannot be resolved by the
mesh. Requires the PDR fields.
+ New lesBuoyantFoam solver for transient, buoyant, turbulent flow of
compressible fluids for ventilation and heat-transfer. Turbulence is
modelled using a run-time selectable compressible LES model.
+ New rhoPimpleFoam solver for transient, turbulent flow of compressible
fluids for ventilation and heat-transfer. Uses the flexible PIMPLE
(PISO-SIMPLE) solution for time-resolved and pseudo-transient simulations.
+ New buoyantSimpleRadiationFoam solver for steady-state, buoyant, turbulent
flow of compressible fluids with radiation, for ventilation and
heat-transfer.
+ New rhoTurbTwinParcelFoam solver for transient for compressible, turbulent
flow with two thermo-clouds.
+ New gnemdFOAM solver for general purpose molecular dynamics that simulates
atoms in arbitrary shaped domains and average atomic/molecular quantities to
the mesh to create field data.
+ New mdEqulibrationFoam solver to equilibrates and/or preconditions molecular
dynamics systems.
+ Demonstration SRFSimpleFoam solver based on simpleFoam that incorporates the
SRF extensions (see below) for rotating flows.
* Automatic mesher
New snappyHexMesh utility that generates split-hex meshes automatically from
triangulated (STL) surface geometries. The mesh approximately conforms to
the surface by iteratively refining a starting mesh and morphing the
resulting split-hex mesh to the surface. An optional phase will shrink back
the resulting mesh and insert cell layers. It has a flexible specification
of mesh refinement level and robust surface handling with a pre-specified
final mesh quality. It runs in parallel with a load balancing step every
iteration.
* Developments to utilities
+ New extrude2DMesh utility that extrudes 2D meshes into a 3D mesh. 2D meshes
are described by faces with 2 points, so can be used in combination with 2D
meshes converted with ccm26ToFoam.
+ New couplePatches functionality integrated into createPatch, which
optionally synchronises ("couples") points and faces of coupled (cyclic,
processor) patches.
+ New applyBoundaryLayer pre-processing utility to apply 1/7th power-law
boundary layers at walls, starting from uniform or potential flow solutions.
+ New execFlowFunctionObjects utility executes functionObjects as a
post-processing activity, e.g. probes, sampling, force calculation.
+ New changeDictionary utility makes batch changes to OpenFOAM input files,
e.g. to change boundary conditions of field files.
+ New foamCalc utility, a generic post-processing field calculator tool
+ New molConfig pre-processing utility for molecular dynamics cases. Fills
zones of a mesh with single crystal lattices of specified structure,
density, orientation, alignment and temperature.
+ Extended splitMeshRegions utility to split multi-zone meshes, e.g. defined
through cellZones, into separate meshes.
+ Extended the foamToVTK, decomposePar, reconstructPar and mapFields utilities
to include support for multiple particle clouds in parallel processing.
* Migration from ParaView 2.4 to ParaView 3.x
+ Rewritten OpenFOAM Reader Module for version 3, a major redesign of
ParaView.
+ New features include viewing patch names, reading of Lagrangian data,
handling of cell, face and point sets, multiple views.
* Model development
+ Overhauled the lagrangian library to support multiple clouds.
+ New lagrangianIntermediate library incorporating a hierarchy of parcel and
cloud types, accommodating kinematic, thermodynamic and reacting
applications, including coupling to the new radiation library. Sub-models
are added at the relevant level of physics, e.g.:
- kinematic: injection, wall interaction, drag, dispersion;
- thermo: heat transfer;
- reacting: reacting composition, mass transfer, surface reactions.
+ New single rotating frame of reference (SRF) library for rotating flow
applications, e.g. turbo-machinery.
+ New radiation library including the P1 model and associated Marshak boundary
conditions for incident radiation.
+ New displacementInterpolation motion solver for flexible mesh scaling.
+ New molecularDynamics Lagrangian library to calculate intermolecular forces
between spherically symmetrical monatomic species in arbitrary geometries.
* New functionObjects
To aid common monitoring and post-processing activities.
+ forces: calculate the force and moment on a patch or set of patches, e.g. to
calculate the lift, drag and moment of an object in the flow.
+ forceCoeffs: calculate the normalised force and moment on a patch or set of
patches, e.g. to calculate the lift, drag and moment coefficients of an
object in the flow.
+ fieldAverage: calculate field arithmetic mean and prime-squared averages for
a list of fields.
+ foamCalcFunctions: calculate field components, div, mag, magGrad or magSqr.
* Improvements to boundary conditions
+ Generalised jumpCyclic type: cyclic condition with an additional prescribed
jump in value.
+ fan type: specialisation of jumpCyclic, applying a prescribed jump in
pressure to simulate a fan within a mesh.
+ Generalised advective outflow boundary condition based on solving D/Dt(psi,
U) = 0 at the boundary.
+ Additional turbulent flow inlet to specify mixing length and frequency.
+ Generalisation of time varying set of boundary conditions.
* Other
+ New argument-free command execution, e.g typing "icoFoam" without root and
case directory arguments.
+ Extended time command line options.
+ Many enhancements to dictionary including macro substitution, optional
merging and default/overwrite behaviour, enhanced "#include" file handling
and the framework to support function evaluation.
+ Cross-links between applications and Doxygen documentation with the "-doc"
argument.
+ Non-blocking, non-buffered, parallel transfers with potential scaling
benefits for larger number of processors.

<h2 id="sec-2">2 GNU/Linux version</h2>
<div id="text-2">
<p>The 64bit binary packs of the OpenFOAM release were compiled on a machine
running SuSE GNU/Linux version 10.3 and the 32bit on a machine running Ubuntu
GNU/Linux version 7.1 and also tested on Ubuntu 8.04. We recommend that
users run OpenFOAM on one of these or a similar recent version of GNU/Linux.
This release has also been successfully compiled and tested on older GNU/Linux
releases but this requires the installation of Qt 4.3.? for ParaView-3 to run.

<div id="text-4">
<ul>
<li>
New rhoCentralFoam solver for high-speed, viscous, compressible flows using
non-oscillatory, central-upwind schemes.
</li>
<li>
New interDyMFoam solver for 2 incompressible, isothermal, immiscible fluids
using a VoF phase-fraction based interface capturing approach, with optional
mesh motion and mesh topology changes including adaptive mesh
(un)refinement. Useful for simulations such as tank filling, sloshing ---
using solid body motion e.g. SDA or SKA (6DoF) &mdash; and slamming (using the
mesh motion solver) and other large-scale applications that benefit from the
efficiency gain of adaptive mesh (un)refinement of the interface.
</li>
<li>
New compressibleInterFoam solver for 2 compressible, isothermal, immiscible
fluids using a volume of fluid (VoF) phase-fraction approach for
interface-capturing. The momentum and other fluid properties are of the
"mixture" and a single momentum equation is solved. Turbulence is modelled
using a run-time selectable incompressible LES model.
</li>
<li>
New interPhaseChangeFoam solver for 2 incompressible, isothermal, immiscible
fluids with phase-change, e.g. cavitation. Uses VoF interface capturing,
with momentum and other fluid properties described for the ``mixture'' and a
single momentum equation is solved. The set of phase-change models provided
are designed to simulate cavitation but other mechanisms of phase-change are
supported within this solver framework.

flow of compressible fluids with radiation, for ventilation and
heat-transfer.

<h2 id="sec-5">5 Automatic mesher</h2>
<div id="text-5">
<p>New snappyHexMesh utility that generates split-hex meshes automatically from
triangulated (STL) surface geometries. The mesh approximately conforms to
the surface by iteratively refining a starting mesh and morphing the
resulting split-hex mesh to the surface. An optional phase will shrink back
the resulting mesh and insert cell layers. It has a flexible specification
of mesh refinement level and robust surface handling with a pre-specified
final mesh quality. It runs in parallel with a load balancing step every
iteration.
