FAQ - Licensing¶
Which types of licenses exist?¶
- There are three types of licenses:
University license
Government institution license
Company license
How many people can use the software simultaneously?¶
- This depends on the type of license:
A University license and a Government institution license are issued to a particular research group (e.g. a professor or group leader) and can be used by all group members simultaneously. The university and government institution licenses can be used on several computers simultaneously. A university license includes 10 computers, a government institution license includes 5 computers.
A Company license applies to a single and named user or a single-PC.
The license is an annual license. After the license has expired, no further simulations can be done. Visualization of previous results of calculations is still possible.
If a user has a valid license, this license can also be installed on a private computer.
Which license do I need for Cluster computing?¶
Only .lic licenses can be used for cluster computing. Any computer that has the free HTCondor software installed can be connected to a licensed computer. There is no need to activate a license for the cluster computers or install nextnano on them. They can be used to execute a batch list of nextnano simulations.
Is there a possibility to evaluate the nextnano software before purchasing?¶
Yes, we offer evaluation licenses with feature restriction. You have to register with an institutional email address. Register now.
If you got granted an evaluation period for a product of the nextnano software,
you will receive an evaluation license key by mail.
Your evaluation license (free-of-charge) will be valid for 1 month starting on the day you receive the mail
and can be activated on 1 computer.
If you need a prolongation, please do not hesitate to contact us.
Note, we reserve the right to not grant an evaluation license,
for example if the same user already used an evaluation license in previous years.
I remember there have been .txt licenses before, what happened to them?¶
.txt has been the extension of our outdated license format. This license format has been abolished due to security risks and is not used anymore. The current format has the .lic extension and enables a wider range of features within the nextnano software.
License activation¶
I don’t have a license (key).¶
Before being able to run any simulations with nextnano software, you need a valid license.
After your purchase order is complete you will receive a license key by mail.
This key is necessary to activate your license.
If you haven’t purchased your license yet, please contact us.
I already purchased a license.¶
For each PC where you want to use nextnano software, you have to activate your license(s). For the online activation, you need an internet connection. There are also possibilities to activate your license without an internet connection. The license activation procedure is documented here: License Activation
Can I activate my license without using nextnanomat?¶
The license activation procedure via command prompt is documented here: License activation via command line.
