CrunchYard offers an engineering simulation service over the Internet on a pay per use basis.

The service allows scientists and engineers to submit simulations which are then run on CrunchYard's system for faster processing through an easy to use interface.

Simulation gallery

Displayed here are a couple of examples showcasing what you can run on the CrunchYard system.The turbine was modelled using Star-CCM+ while the rest were modelled in FEKO.

What type of applications do CrunchYard have on its system ?

CrunchYard can run most multi cpu capable simulation software. The most commonly used applications: STAR-CCM+, LAMMPS, GAMESS and FEKO are listed here. Many applications avialable upon request. Custom applications like DCIP, H3DTD, TDOCT available to approved users.

Need more processing power ?

Run a large simulation faster, or run lots of small simulations at the same time on CrunchYard's system, providing quicker turn around time for finding those important answers.

Can't afford your own super computer ?

Making use of CrunchYard's cluster means you don't have to buy and manage your own equipment. Just use CrunchYard's services as the need arises.

CPMD, designed for molecular dynamics, is now available on request

The online simulation platform, CrunchYard, has made CPMD available to users.

The CPMD code is a plane wave/pseudopotential implementation of Density Functional Theory, particularly designed for ab-initio molecular dynamics. Its first version was developed by Jurg Hutter at IBM Zurich Research Laboratory starting from the original Car-Parrinello codes.

The current version, 3.17, is copyrighted jointly by IBM Corp and by Max Planck Institute, Stuttgart, and is distributed free of charge to non-profit organizations. Profit organizations interested at the code should contact CPMD.

To start using CPMD on CrunchYard, create and account at and agree to the terms and conditions. Register an account at or contact Dr Renier Dreyer at +27 (0)11 717 6379 and request CPMD access on the HPC facility.
