This wiki aims to showcase how [http://openfoam.com/ OpenFOAM], the leading open source software for Computational Fluid Dynamics (CFD), can be easily ported to and used on a public e-Infrastructure such as EGI.
 
 
 
=== About ===
 
The NACA airfoils are [https://en.wikipedia.org/wiki/Airfoil airfoil] shapes for aircraft wings developed by the [https://en.wikipedia.org/wiki/National_Advisory_Committee_for_Aeronautics National Advisory Committee for Aeronautics (NACA)].
 
In this wiki we will show the wind effect (pressure, velocity) simulated using the CFD software, OpenFOAM supported by CFD Support.
 
 
 
== Access the UberCloud HPC Container ==
 
The Docker based HPC container has been successfully installed at CESNET-MetaCloud, one of the cloud provider of the EGI Federation.
 
 
 
If you are interested to access and use the UberCloud HPC container on the EGI infrastructure, please send an e-mail to business@egi.eu to get your individual credentials.
 
 
 
The credential will be valid for up to <b>24</b> hours within a specifically scheduled time (first come first served). Once you have your credential, please connect to this [https://egi-openfoaminbox.theubercloud.net/ link].
 
 
 
After a successfully authentication this is how the HPC container looks like:
