A. Running OpenFOAM in 32-bit mode
|
||||
* System requirements
|
||||
OpenFOAM is developed and tested on Linux, but should work with other Unix
|
||||
style systems. To check your system setup, execute the foamSystemCheck script
|
||||
in the bin/ directory of the OpenFOAM installation. If no problems are
|
||||
reported, proceed to "3. Installation"; otherwise contact your system
|
||||
administrator.
|
||||
|
||||
If the user wishes to run OpenFOAM in 32/64-bit mode they should consult the

*** Installation in alternative locations
|
||||
OpenFOAM may also be installed in alternative locations. However, the
|
||||
installation directory should be network available (e.g., NFS) if
|
||||
parallel calculations are planned.

4. Building from Sources (Optional)
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
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 http://gcc.gnu.org/.

|
||||
which may be obtained from http://gcc.gnu.org/.
|
||||
|
||||
Install the compiler in

|
||||
@ -112,68 +87,54 @@
|
||||
environment variables as in section 3.
|
||||
|
||||
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 <enquiries@OpenCFD.co.uk> to
|
||||
negotiate a support contract and we will do the port and maintain it for
|
||||
future releases.

|
||||
* Testing the installation
|
||||
To check your installation setup, execute the 'foamInstallationTest' script
|
||||
(in the bin/ directory of the OpenFOAM installation). If no problems are
|
||||
reported, proceed to getting started with OpenFOAM; otherwise, go back and
|
||||
check you have installed the software correctly and/or contact your system
|
||||
administrator.

||||
5. Testing the installation
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
To check your installation setup, execute the 'foamInstallationTest'
|
||||
script (in the bin/ directory of the OpenFOAM installation). If no
|
||||
problems are reported, proceed to getting started with OpenFOAM;
|
||||
otherwise, go back and check you have installed the software correctly
|

|
||||
|
||||
|
||||
6. Getting Started
|
||||
~~~~~~~~~~~~~~~~~~
|
||||
* Getting Started
|
||||
Create a project directory within the $HOME/OpenFOAM directory named
|
||||
<USER>-<VERSION> (e.g. 'chris-1.5' for user chris and OpenFOAM version 1.5)
|
||||
and create a directory named 'run' within it, e.g. by typing:
|
||||
|
||||
mkdir -p $HOME/OpenFOAM/${USER}-${WM_PROJECT_VERSION}/run
|
||||
+ mkdir -p $HOME/OpenFOAM/${USER}-${WM_PROJECT_VERSION}/run
|
||||
|
||||
Copy the 'tutorial' examples directory in the OpenFOAM distribution to the
|
||||
'run' directory. If the OpenFOAM environment variables are set correctly,
|
||||
then the following command will be correct:
|
||||
|
||||
cp -r $WM_PROJECT_DIR/tutorials $HOME/OpenFOAM/${USER}-${WM_PROJECT_VERSION}/run
|
||||
+ cp -r $WM_PROJECT_DIR/tutorials
|
||||
$HOME/OpenFOAM/${USER}-${WM_PROJECT_VERSION}/run
|
||||
|
||||
Run the first example case of incompressible laminar flow in a cavity:
|
||||
|
||||
cd $HOME/OpenFOAM/${USER}-${WM_PROJECT_VERSION}/run/tutorials/icoFoam/cavity
|
||||
blockMesh
|
||||
icoFoam
|
||||
+ cd $HOME/OpenFOAM/${USER}-${WM_PROJECT_VERSION}/run/tutorials/icoFoam/cavity
|
||||
+ blockMesh
|
||||
+ icoFoam

#+TITLE: *OpenFOAM release notes for version 1.5*
|
||||
#+AUTHOR: OpenCFD Ltd.
|
||||
#+DATE: 10 July 2008
|
||||
#+LINK: http://www.opencfd.co.uk
|
||||
|
||||
* 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 10.2 and the 32bit on a machine running Ubuntu
|
||||
GNU/Linux version 7.1. The release has also been tested on SuSE 10.0, 10.3
|
||||
and Ubuntu 8.04. We recommend that users run OpenFOAM on one of these or a
|
||||
similar recent version of GNU/Linux.
|
||||
|
||||
* 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.
