CUBIT Licensing

Cubit is available for US goverment use only, and requires proof of a current US government contract. If your work is not US government use, you can use Trelis, the commercial version of Cubit, available through csimsoft, which is available for purchase for any use, including academic and commercial.

The instructions below are for US government use of Cubit only. If your work is not US government use, go to csimsoft.

Unfortunately, due to new requirements for review, processing and approval from the DOE, all new Cubit license requests are currently on hold. We will complete the processing of your request as soon as the DOE has approved the new process and it has been implemented.

CUBIT is available on Windows, Mac, and Linux platforms.

Obtaining a CUBIT License


There is no charge for U.S. government-use licenses of CUBIT.

Government Use Licenses

Licenses are available to U.S. Government Agencies (i.e. military, government labs and/or agencies). Limited-term licenses are also available to companies performing work under contract issued directly by a U.S. Government entity. To obtain a license, please use the following procedure:

U.S. Government Agencies and direct Contractors to the U.S. Government, please click: GOVERNMENT REQUESTORS ONLY to fill out the online request (Participant Data Sheet).

Complete the necessary information, then submit the form by clicking the button at the bottom of the Participant Data Sheet.

Once the Online Participant Data Sheet has been submitted a Cubit licensing liaison will initiate the approval process. Assuming no additional information is required for the request, a license agreement will be sent via email for review and signature, if required.

Important: A step in the licensing process requires that an original of the signed license agreement be returned to Sandia within 30 days of receipt of password. Failing to send a hardcopy will result in cancellation of the license agreement and download privileges revoked.
