Openfoam

OpenFOAM Ubuntu repository To use the OpenFOAM early-release Ubuntu repository, you will need to add the signing key and the repository location (s) to your system. This typically only needs to be done once per distribution. The most convenient way is to use the installer script with one of these commands. OpenFOAM-dev is the development line of OpenFOAM. It is packaged weekly for Ubuntu, which can be installed directly on Windows 10 and is incorporated into Docker builds for other Linux distributions. OpenFOAM® for Windows Description Download OpenFOAM® for Windows When running OpenFOAM® in Windows we recommend to use Cygwin software to keep the workflow consistent with Linux as much as possible. There are many other ways of using OpenFOAM® for Windows, depending on your previous experiences, preferred applications and other circumstances. OpenFOAM. (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 computational fluid dynamics (CFD). It is a unique, and highly extensible, software development kit (“devkit”) for CFD, consisting of 1 million lines of C code.

User OpenFOAM® training detail

We would like to offer our User OpenFOAM® training to all those who are new to OpenFOAM®, have no experience in this area whatsoever, but it may be also of interest for those who have already experienced OpenFOAM® in the past and want to improve their skills. In two days, divided into four thematic sections, the trainee receives an overview of the possibilities of OpenFOAM®. They learn to run different types of CFD simulations, set the boundary conditions and parameters for calculations, prepare computational meshes and evaluate the results.

Advanced OpenFOAM® training detail

The Advanced OpenFOAM® training is suitable for participants of User training and also for those who already have an existing OpenFOAM® user experience and want to continue and develop their special skills even further. The two-day advanced training is also spread into four thematic blocks. You will look at the source code and gradually implement and test advanced techniques for preprocessing, postprocessing, editing solvers, boundary conditions and turbulence models.

Day 1Day 2
∇ orientation in the source code of OpenFOAM®
∇ implementation of the new OpenFOAM® solver

Each participant can bring a test case, or the problem that he/she would like to solve using OpenFOAM®. Our lecturers will advice him/her and recommend him/her the most suitable solution.

Turbulence training detail

Openfoam

Turbulence training is a special CFD workshop (performed in OpenFOAM®), which guides a trainee over various CFD Turbulence modeling methods. On standard benchmark test cases the turbulence modeling methods are discussed aiming on their benefits and drawbacks.

OpenFOAM is a free, open source CFD software packaage.

This entry provides basic information on how to run OpenFOAM from Open CFD.NB OpenFOAM is still in testing, and this guide is very liable to change.

General OpenFOAM documentation¶

OpenFOAM is complex, and you should start by reading the official documentation at http://www.openfoam.org/docs/user

Setting up the environment¶

You can set up the environment variables necessary to run both OpenFOAM version 2.3.0 and ParaView version 4.1.0 by loading the openfoam environment module.

This module also sets up environment variables that define default locations for your OpenFOAM cases and binaries.

OpenfoamOpenfoam

The ~ means your login directory.

The first time you use OpenFOAM, you should create these directories with the commands below and use them for your OpenFoam cases.

Getting Started¶

Create the project directories above.

Copy the tutorial examples directory in the OpenFOAM distribution to the run directory.

Run the first example case of incompressible laminar flow in a cavity:

Now refer to the OpenFOAM User Guide to get more information!

Launching on the login node¶

Visualisation of OpenFOAM results can be done using paraFoam at the command prompt; i.e.:

Warning

If you’re visualising large data sets this should NOT be done on the login nodes, since this can use a considerable amount of RAM and CPU. Instead, you should request an interactive job with UGE (SGE).

Using Univa Grid Engine¶

Univa Grid Engine (UGE) allows both interactive and batch jobs to be submitted, with exclusive access to the resources requested.

Running through an interactive shell¶

To launch paraFoam interactively, displaying the full GUI:

In the above command, hh:mm:ss is the length of real-time the shell will exist for, -cwd- means use the current working directory and -V- exports the the current environment.e.g. to run paraFoam for 1 hour:

This will run paraFoam within the terminal from which it was launched. You will need to be in an appropriate directory for paraFoam to find the correct files.

Batch Execution¶

To run OpenFOAM in batch-mode you first need to setup your case.

A script must then be created that will request resources from the queuing system and launch the desired OpenFOAM executables

eg script runfoam.sh:

This can be submitted to the queuing system using:

Parallel Execution¶

If you’ve configured your OpenFOAM job to be solved in parallel, you need to submit it differently. It uses its own private version of OpenMPI 1.6.5 so you don’t need to explicitly load an openmpi module. This is an example of a suitable submission script that reserves 2GB RAM per slot.

NB there is a space between ”.” and “/etc/profile.d/modules.sh” in the script below!
