Computer-Aided Engineering in the EGI FedCloud

This wiki aims to showcase how 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 airfoil shapes for aircraft wings developed by the 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 24 hours within a specifically scheduled time (first come first served). Once you have your credential, please connect to this link.

After a successfully authentication this is how the HPC container looks like:
