The GPL gives users the freedom to modify and redistribute the software and a guarantee of continued free use, within the terms of the licence.

Since then, OpenFOAM has continued to be managed and developed with new versions being released to the public each year. The current version is 7. Contributions are made under the OpenFOAM Contributor Agreement to facilitate enforcement of the free, open source licencesigned either by the individual, or by the organisation that employs them. OpenFOAM includes hundreds of robust CFD applications built from the devkit, which can be extended and customised, quickly and conveniently.

The applications are used to create CFD simulations by industry, academic, and research and government institutes, across all fields of engineering and science. It ensures that OpenFOAM is developed and maintained to meet broad needs of all users, rather than to limited needs of one or two large corporations. Compare that to some single-user licences of commercial CFD software that are times more expensive! Instead, organisations with commercial dependence on OpenFOAM should contribute to the cost of sustaining it.

OpenFOAM v6 User Guide: 5.3 Mesh generation with blockMesh

The latest version of OpenFOAM includes new tools to enable more productive CFD : post-processing command line interface; template cases; case setup, e.In this chapter we shall describe in detail the process of setup, simulation and post-processing for some OpenFOAM test cases, with the principal aim of introducing a user to the basic procedures of running OpenFOAM.

Before attempting to run the tutorials, the user must first make sure that OpenFOAM is installed correctly. The tutorials are organised into a set of directories according to the type of flow and then subdirectories according to solver.

The user can copy cases from the tutorials directory into their local run directory as needed. Read More. See our Essential CFD and Applied CFD courses for details Essential CFD Introduction to meshes : meshing strategy, blockMesh quick start, boundary types, patch groups snappyHexMesh introduction : surface patching, castellated mesh, surface snapping snappyHexMesh enhancements : assessing mesh quality, layer insertion, cell refinement introduction snappyHexMesh refinement : tri-surface manipulation, surface refinement, region refinement, more on layers.

Each application performs a specific task within a CFD workflow. The snappyHexMesh application, for example, is a mesh generator for complex geometry, which could be used to generate a mesh around a vehicle. The simpleFoam application could then be used to simulate steady-state, turbulent, incompressible flow around the vehicle.

Alternatively, a transient simulation could be run with the pimpleFoam application. The OpenFOAM User Guide describes these applications and how to execute them, either on a single processor or in parallel on multiple processors.

The input data includes time information start time, end time, time step, etc and controls for reading and writing data time, format, compression, etc. It describes the setting of numerical schemes that affects accuracy and stability of a simulation. Matrix solver controls and algorithm controls are also explained that affect computational time and stability. The blockMesh application for generating meshes of simple geometries is described in detail, followed by the snappyHexMesh application and its control parameters.

OpenFOAM includes applications that convert meshes from well known formats into the OpenFOAM format and detailed coverage is given to the principle conversion applications, e. The mapFields application maps field data, e.

It provides new functionality and major improvements to existing code, with strict demands on usability, robustness and extensibility. OpenFOAM 7 includes the following key developments:. Uses Docker to provide a self-contained environment that includes code, runtime, system tools and libraries, independent of the underlying operating system.

OpenFOAM 7 includes the following key developments: Heat transfer: consolidated solvers and improved convergence and robustness.

User Guide

Particle tracking: improved robustness and optimized computation. Multiphase: wave damping, configurable inlet phase properties, better settling numerics. Reacting multiphase models: heat transfer, population balance, breakup, coalescence, etc. Turbulence: improved consistency and stability of wall functions, added sources. Thermophysical: thermodynamic functions, temperature-strain-dependent viscosity.

Other models: atmospheric, rigid body dynamics, boundary conditions, sources. Mesh: standardized dynamic mesh capability, improved motion solvers. Case Configuration: improved data visualization, setup tools, function objects.

Computation: improvements to containers, fields, parallel running, etc.OpenFOAM includes a large range of solvers each designed for a specific class of problem. The equations and algorithms differ from one solver to another so that the selection of a solver involves the user making some initial choices on the modelling for their particular case.

It ultimately determines many of the parameters and physical properties required to define the case but leaves the user with some modelling options that can be specified at runtime through the entries in dictionary files in the constant directory of a case. This chapter deals with many of the more common models and associated properties that must be specified at runtime.

Contrary to what is stated in table 4. Non-orthogonal correctors are here to save you if your code is blowing up because the mesh is so non-orthogonal that the first solution is driving the velocity to be stupid.

If your velocity is OK, you just keep doing "normal" correctors, without special need for non-orthogonal ones. I use them on bad meshes, when the solver is giving me trouble. Usually, 1 is enough, and I never used more than 3. Section 5. By adding the following lines instead of the standard featureCos 0.

Where the separationVector is the vector between the two parts of the patch. If rotational patch is preferred, it can be specified by:. Where the rotational axis and the rotational centre can be specified by the two vectors above. This gives you obj files of the patches and lines connecting each face. These can be visualized in paraview by conversion using objToVTK.

In section 5. Looking at the source I would say that this problem is already fixed by the current versions of starToFoam but I can't test this theory because I have no StarCD.

Body may only rotate around an axis fixed in global space. Axial angular spring with moment values drawn from an interpolation table. Linear damping. By dropping FoamX and avoiding the additional work of creating a java-compatible interface for each featurethe developers could introduce very interesting and useful dictionary functionality fairly quickly:.
