Introduction

OpenFOAM is a free, open source CFD software package developed by OpenCFD Ltd at ESI Group and distributed by the OpenFOAM Foundation. To test ONELAB models working with OpenFOAM, a working installation of OpenFOAM on your system is needed. The easiest way to do so, is to install first the generic ONELAB virtual machine by following these instructions. When done, log in into the virtual machine (username: "olvm", passwd: olvm) and proceed with the Instructions of the next section.

Installation

The Virtual machine is configured so that Gmsh and OpenFOAM can be installed straightforwardly. You have to be online. Proceed as follows.

Step 1 - Download installation scripts

Open a terminal by clicking on the "terminal" icon in the launcher panel and issue the command

install_scripts.sh

Step 2 - Install Gmsh and Onelab

Then the command

install_gmsh.sh

downloads the nightly-build of Gmsh from http://geuz.org/gmsh, install it, and place a Gmsh icon on the Desktop.

Step 3 - Install OpenFOAM

The command

install_foam.sh

installs OpenFOAM 2.30 from http://www.openfoam.org. Simply answer "Y" or "y" when asked to.

After these 3 steps, you have a woking installation of Gmsh and OPenFOAM on the virtual machine.

Step 4 - Download model examples

The model examples detailed in the next section are downloaded in a directory named FOAMMODELS with the command
