OpenFOAM at a glance

Purpose: Computational Fluid Dynamics
Latest version: 5.0
Availability: All
Licence: Open Source
Documentation: User's Guide

OpenFOAM is a software environment for computational fluid dynamics (CFD) and related computations.

OpenFOAM provides a C++ library and tools for setting up, meshing, solving, computing properties, and post-processing continuum mechanics, especially computational fluid dynamics. OpenFOAM includes solvers for a number of applications and provides an environment in which users can build their own.

A more detailed description can be found here.

 

 

Licence

OpenFOAM operates under a GNU GPL licence.

 

 

Available Versions

The currently available versions of OpenFOAM in our facilities are:

  • 1.7.1
  • 2.0.0
  • 2.2.0
  • 2.2.1
  • 2.3.1
  • 3.0.0
  • 1606+
  • 4.1
  • 1612+
  • 5.0

We provide an automatic configuration script to set up the environment for any version of OpenFOAM. To use it, run the following command in the target machine:

source config_OF 300

where 300 refers to version 3.0.0, and would be replaced, for instance, by 231 for 2.3.1 or 1606 for v1606+.

You can use this command to print a list of versions available in your current machine:

config_OF -h

And this command allows you to check an installation:

test_OF 1606

Benchmark

OpenFOAM benchmark at Pirineus: actual speed-up (green) and ideal speed-up (blue) vs. number of cores for a calculation (motorBike tutorial) with OpenFOAM 2.0.0 involving 60·106 elements, simpleFOAM solver.
