|
* Overview
|
|
OpenFOAM-dev is the latest major release of OpenFOAM including many new
|
|
developments a number of bug-fixes. This release passes our standard tests
|
|
and the tutorials have been broadly checked. Please report any bugs by
|
|
following the link: http://www.openfoam.com/bugs.
|
|
|
|
* GNU/Linux version
|
|
This release of OpenFOAM is distributed primarily in 2 ways: (1) as a Debian
|
|
pack containing binaries and source; (2) from the SourceForge source code
|
|
repository (see [[./README.org][README]]).
|
|
|
|
The Ubuntu/Debian pack is available for 32 and 64 bit versions of the 10.04
|
|
LTS operating system using the system compiler and libraries that will be
|
|
installed automatically from standard Debian packs.
|
|
|
|
To use the source version from the SourceForge repository, we provide a source
|
|
pack of third-party packages that can be compiled on the user's system. This
|
|
does not include =gcc=, since the system installed version is typically
|
|
sufficient, but includes =paraview-3.8.0=, =openmpi-1.4.1=, =scotch_5.1=, =metis-5.0pre2=, =ParMetis-3.1= and =ParMGridGen-1.0=.
|
|
|
|
* Library developments
|
|
There have been a number of developments to the libraries to support the
|
|
extension of functionality in solver and utility applications.
|
|
*** Core library + Large number of code refinements and consistency improvements to support
|
|
other developments.
|
|
*** Turbulence modelling
|
|
*** Thermo-physical Models
|
|
*** DSMC
|
|
*** Dynamic Mesh
|
|
*** Numerics
|
|
*** *Updated* command line help, e.g. `snappyHexMesh -help' now gives:
|
|
|
|
Usage: snappyHexMesh [OPTIONS]
|
|
options:
|
|
-case <dir> specify alternate case directory, default is the cwd
|
|
-overwrite overwrite existing mesh/results files
|
|
-parallel run in parallel
|
|
-srcDoc display source code in browser
|
|
-doc display application documentation in browser
|
|
-help print the usage
|
|
|
|
*** *New* Surface film library
|
|
+ Creation of films by particle addition, or initial film distribution + Coupled with the lagrangian/intermediate cloud hierarchy library
|
|
+ Hierarchical design, consisting of + kinematic film: mass, momentum
|
|
+ constant thermodynamic properties + thermodynamic film: mass, momentum and enthalpy
|
|
+ constant, or temperature dependant thermodynamic properties + Sub-models:
|
|
+ detachment/dripping whereby particles (re)enter the originating cloud + particle sizes set according to PDF
|
|
+ other properties set to ensure mass, momentum and energy conservation + heat transfer to/from walls and film surface
|
|
+ film evaporation and boiling + Additional wall functions for primary region momentum and temperature
|
|
taking film into account
|
|
+ Parallel aware
|
|
*** *Updated* particle tracking algorithm
|
|
|
|
* Solvers
|
|
A number of new solvers have been developed for a range of engineering
|
|
applications. There has been a set of improvements to certain classes of
|
|
solver that are introduced in this release.
|
|
*** *New* Solvers + =reactingParcelFilmFoam=: Lagrangian cloud and film transport in a
|
|
reacting gas phase system
|
|
*** Modifications to multiphase and buoyant solvers
|
|
+ ...
|
|
*** Modifications to solvers for sensible enthalpy + ...
|
|
*** Modifications to steady-state compressible solvers
|
|
+ ...
|
|
*** Other modifications + ...
|
|
|
|
* Boundary conditions
|
|
New boundary conditions have been introduced to support new applications in
|
|
OpenFOAM.
|
|
+ *New* wall functions: + kappatJayatillekeWallFunction: incompressible RAS thermal wall function
|
|
|
|
* Utilities
|
|
There have been some utilities added and updated in this release.
|
|
*** *New* utilities
|
|
+ =extrudeToRegionMesh=: Extrude faceZones into separate mesh (as a
|
|
different region) + used to e.g. extrude baffles (extrude internal faces) or create
|
|
liquid film regions
|
|
+ if extruding internal faces: + create baffles in original mesh with directMappedWall patches
|
|
+ if extruding boundary faces: + convert boundary faces to directMappedWall patches
|
|
+ extrude edges of faceZone as a <zone>_sidePatch
|
|
+ extrude edges inbetween different faceZones as a
|
|
(nonuniformTransform)cyclic <zoneA>_<zoneB> + extrudes into master direction (i.e. away from the owner cell
|
|
if flipMap is false)
|
|
*** Updated utilities
|
|
+ ...
|
|
|
|
* Post-processing + =foamToEnsight=: new =-nodeValues= option to generate and output nodal
|
|
field data.
|
|
+ Function objects: + =residualControl=: new function object to allow users to terminate steady
|
|
state calculations when the defined residual levels are achieved
|
|
+ =abortCalculation=: watches for presence of the named file in the
|
|
$FOAM_CASE directory and aborts the calculation if it is present + =timeActivatedFileUpdate=: performs a file copy/replacement once a
|
|
specified time has been reached, e.g. to automagically change fvSchemes and
|
|
fvSolution during a calculation
|
|
+ =streamLine=: generate streamlines; ouputs both trajectory and field data
|
|
|
|
* New tutorials
|
|
There is a large number of new tutorials to support the new solvers in the
|
|
release. + =reactingParcelFilmFoam= tutorials:
|
|
+ multipleBoxes, hotBoxes, panel, evaporationTest
