Frequently Asked Questions

If you buy a subscription license, you’ll always be able to use the latest version of the software for a regular fee. Support & e-training are included, as is 2D Ambiens, our 2D-CFD package. 

Perpetual licenses have a one-off upfront fee for unlimited access to a particular version of Tas Engineering. These are licensed via USB dongle, which you can plug into the computer you wish to use Tas on. Perpetual licenses do not include software support and Ambiens 2D. 

If you purchase a maintenance and support contract alongside your perpetual license, for a regular fee, you’ll be able to use the latest version of the software and be entitled to software support and e-training material.

Digital subscription licenses offer the most flexibility and convenience, with no large upfront fee. They can be managed at any time from your account or by contacting us.
