OpenFOAM ( Open Source Field Operation and Manipulation ) is a numerical, free simulation software package for continuum mechanical problems written in C ++ . The main focus is on solving fluid flow problems ( Numerical Fluid Mechanics (English) CFD).
Program content
In addition to many predefined standard solvers for fluid mechanics including multiphase flows, there are other solvers, including for the following physical problems:
Further solvers can be added in OpenFOAM's own syntax.
Turbulence can be mapped using RANS , coarse structure simulation or direct numerical simulation .
In order to be able to solve systems of partial differential equations , the following discretization schemes are implemented as a C ++ program library in OpenFOAM :
- Finite Volume Method (FVM),
- Finite element method and
- Finite surfaces method ( Finite Area ).
The preparation of a simulation (preprocessing) takes place in OpenFOAM with the help of the included tools on the command line without a GUI . But it is also possible to use external programs and then import the generated networks into OpenFOAM. The simulation parameters are also set here via the command line.
The graphic preparation of the simulation results ( postprocessing ) is done by default using the ParaView software . Alternatively, the results can be exported in the formats of some widely used, commercial visualization programs such as Tecplot360 or FieldView.
OpenFOAM is increasingly used in courses at universities.
history
The development of FOAM ( Field Operation And Manipulation ) was started around 1989 by Henry Weller at Imperial College London in the research group of Professor AD Gosman. Doctoral students like Hrvoje Jasak from the research group used and expanded FOAM as part of their doctoral thesis. Weller, Jasak and other members of the research group such as Greenshields and Janssens founded the company Nabla Ltd. in 2000. to offer FOAM commercially. In 2004 the company was dissolved and the developers Weller (OpenCFD Ltd.) and Jasak (Wikki Ltd.) continued to work separately on "OpenFOAM", which is now under the GNU General Public License .
On August 15, 2011, the takeover of the developer company OpenCFD Ltd. announced by SGI . At the same time, the no- shares company or a non-profit organization with the name OpenFOAM Foundation, with the directors Mark Barrenechea (CEO, SGI) and Henry Weller (founder of OpenFOAM), was founded in Delaware, USA , with the mandate distribute the current and future versions of OpenFOAM under the GPL . A little more than a year later, on September 12, 2012, it was announced that the ESI Group would take over OpenCFD Ltd., the OpenFOAM Foundation and all trademark rights. In 2014 Henry Weller and Chris Greenshields left OpenCFD Ltd. to lead the OpenFOAM Foundation , which had moved to the UK , as directors and to offer training and software development for OpenFOAM with the company CFD Direct.
Derived programs and projects
- OpenFOAM (formerly OpenFOAM +) is the variant developed by ESi, which is derived from the Foundation Version 3.0.x.
- The Extend Project with its version "foam-extend-4.0" developed by the developer community, which is based on the OpenFOAM-1.6 version and additional functions such as " Radial Basis Function ", "General Grid Interface (GGI)", "Finite Areas -Method (Finite Area Method, FAM) ”or“ Block Coupled Matrix Solver ”. The developer community around the Extend Project has also organized the "Openfoam Workshop", which has been held annually since 2006.
- FreeFOAM does not offer any additional functionality compared to OpenFOAM, but tries to facilitate portability to other operating systems by using CMake instead of OpenFOAM's own "wmake" ( Weller make). The FreeFOAM conversion to CMake was used by a developer of the Extend Project to implement a native port to Microsoft Windows . FreeFOAM is no longer actively developed.
- caelus-CML is an OpenFOAM fork and is called the "Computational Mechanics Library" to indicate the wide range of possible uses in the area of CAE . The native portability to the operating systems (Mac, Linux and Windows) is achieved at caelus with SCons as the build system.
- blueCFD-core is one with MinGW cross compiled Windows porting.
Graphical user interfaces (GUIs) and tools for working with OpenFOAM
- BIM HVACTool is a GUI for building simulation with OpenFOAM from TIAN Building Engineering
- SwiftBlock and SwiftSnap are two Python plug-in scripts for Blender that make it easier to create the configuration files `blockMeshDict` and` snappyHexMeshDict`.
- HELYX-OS is a graphical user interface for working with the automatic networking program snappyHexMesh.
- MantiumFlow is a CLI and GUI for OpenFOAM. Pre- and post-processing are completely automated into apps.
- SimScale is a cloud-based simulation software that integrates OpenFOAM and other solvers.
- Sim-Flow is a GUI for OpenFOAM. The RapidCFD variant from the same manufacturer also offers GPU-based equation solvers.
- iconCFD is another commercial version of OpenFOAM with a graphical user interface.
- visualCFD is a commercial user interface for OpenFOAM distributed by ESi.
- InsightCAE is an open source project to automate simulation processes for special applications and to provide them with a GUI ("vertical apps"). OpenFOAM is used as the backend for CFD simulations.
- FEATool Multiphysics is an application programmed in the Octave / MATLAB m-code script language
- CastNet is a commercial GUI for OpenFOAM with direct CAD kernel import, integrated mesh generator and snappyHexMesh support. The OpenFOAM versions are supported by ESI, the OpenFOAM Foundation and blueCFD-Core.
