Open. FOAM Wikipedia. Open. FOAM for Open source Field Operation And Manipulation is a C toolbox for the development of customized numerical solvers, and pre post processing utilities for the solution of continuum mechanics problems, including computational fluid dynamics CFD. The code is released as free and open source software under the GNU General Public License. The Open. FOAM name was registered by Open. CFD Ltd5 in 2. 00. Open. FOAM Foundation Ltd in 2. Historyedit. Flow simulation using Open. FOAM and Para. View for visualization. Open. FOAM originally, FOAM was created by Henry Weller from the late 1. Imperial College, London, to develop a more powerful and flexible general simulation platform than the de facto standard at the time, FORTRAN. This led to the choice of C as programming language, due to its modularity and object oriented features. In 2. 00. 4, Henry Weller, Chris Greenshields and Mattijs Janssens founded Open.

At the same time, the copyright of Open. FOAM was transferred to the Open. FOAM Foundation, a newly founded, not for profit organisation that manages Open.

OpenFOAM for Open source Field Operation And Manipulation is a C toolbox for the development of customized numerical solvers, and prepostprocessing utilities. Dear all, I have to set up two possible configurations for a workstation, one around 7000 and the otherone around 12000, and one of them will be. PRINCIPIA is a engineering company developing addedvalue offer to Energy sector and to Naval Defense sector. With more than 30 years of industrial background. FOAM and distributes it to the general public. On 1. 2 September 2. ESI Group announced the acquisition of Open. Cfd Software Fluent' title='Cfd Software Fluent' />CFD Ltd from SGI. In 2. Weller and Greenshields left ESI Group and continue the development and management of Open. FOAM, on behalf of the Open. FOAM Foundation, at CFD Direct. CFD Direct continued the development of the distribution known as Open. FOAM, whereas the ESI group now independently develops a fork known as Open. FOAM plus. Distinguishing featureseditOne distinguishing feature of Open. FOAM is its syntax for tensor operations and partial differential equations that closely resembles the equations being solved. For example,1. 0 the equationUtUUpdisplaystyle frac partial rho mathbf U partial tnabla cdot phi mathbf U nabla cdot mu nabla mathbf U nabla pis represented by the codesolvefvm ddtrho,Ufvm divphi,U fvm laplacianmu,U fvc gradp This syntax, achieved through the use of object oriented programming and operator overloading, enables users to create custom solvers with relative ease. However, code customization becomes more challenging with increasing depth into the Open. FOAM library, owing to a lack of documentation and heavy use of template metaprogramming. ExtensibilityeditUsers can create custom objects, such as boundary conditions or turbulence models, that will work with existing solvers without having to modify or recompile the existing source code. Open. FOAM accomplishes this by combining virtual constructors with the use of simplified base classes as interfaces. As a result, this gives Open. FOAM good extensibility qualities. Open. FOAM refers to this capability as run time selection. Structure of Open. FOAMeditOpen. FOAM is constituted by a large base library, which offers the core capabilities of the code Tensor and field operations.

The capabilities provided by the library are then used to develop applications. Applications are written using the high level syntax introduced by Open. FOAM, which aims at reproducing the conventional mathematical notation. Two categories of applications exist Solvers they perform the actual calculation to solve a specific continuum mechanics problem. Utilities they are used to prepare the mesh, set up the simulation case, process the results, and to perform operations other than solving the problem under examination. Each application provides specific capabilities for example, the application called block. Mesh is used to generate meshes from an input file provided by the user, while another application called ico. Foam solves the NavierStokes equations for an incompressible laminar flow. Finally, a set of third party packages are used to provide parallel functionality Open. MPI and graphical post processing Para. View. CapabilitieseditOpen. FOAM solvers include 2. Basic CFD solvers. Incompressible flow with RANS and LES capabilities2. Compressible flow solvers with RANS and LES capabilities2. Buoyancy driven flow solvers2. DNS and LESMultiphase flow solvers2. Particle tracking solvers. Solvers for combustion problems2. Solvers for conjugate heat transfer2. Molecular dynamics solvers2. Direct simulation Monte Carlo solvers2. Electromagnetics solvers2. Pixelmon 3.02. Solid dynamics solvers3. In addition to the standard solvers, Open. FOAM syntax lends itself to the easy creation of custom solvers. Open. FOAM utilities are subdivided into Mesh utilities. Mesh generation they generate computational grids starting either from an input file block. Mesh, or from a generic geometry specified as STL file, which is meshed automatically with hex dominant grids snappy. Hex. MeshMesh conversion they convert grids generated using other tools to the Open. FOAM format. Mesh manipulation they perform specific operations on the mesh such as localized refinement, definition of regions, and others. Parallel processing utilities they provide tools to decompose, reconstruct and re distribute the computational case to perform parallel calculations. Pre processing utilities tools to prepare the simulation cases. Post processing utilities tools to process the results of simulation cases, including a plugin to interface Open. FOAM and Para. View. Surface utilities. Thermophysical utilities. LicenseeditOpen. FOAM is free and open source software, released under the GNU General Public License version 3. Advantages and disadvantageseditAdvantageseditFriendly syntax for partial differential equations. Fully documented source code3. Unstructured polyhedral grid capabilities. Automatic parallelization of applications written using Open. FOAM high level syntax. Wide range of applications and models ready to use. Commercial support and training provided by the developers. No license costs. DisadvantageseditThe development community suffers from fragmentation, giving rise to numerous forked projects. Absence of an integrated graphical user interface stand alone open source and proprietary options are availableThe Programmers guide does not provide sufficient details, making the learning curve very steep if you need to write new applications or add functionality.
