Free Academic License

For VNL & ATK-ForceField

ATK-ForceField package is included for free as well. However, ATK-DFT, ATK-SE and the VASP plugins are not included.
Note: An academic email address is strictly required.
ATK On-Demand

Pay-as-you-go cloud license

All you need is a license for VNL and an ATK On-Demand account, then use the Job Manager in VNL to submit jobs directly to the remote cluster. This gives you the option to execute small or very demanding jobs, using anything from just a few to several hundred cores, without having to commit to any up-front payment of the license fees.
This option is ideal if you do not have your own cluster - and also if you have license/cluster but need to boost your capacity temporarily.
