Design Simulation Technologies Introduces Token-Based Licensing for Working Model 2D and SimWise 4D

New usage-based licensing option lets commercial customers access DST simulation tools on demand, drawing a token only on the days they run them

(Canton, MI) – June 1, 2026 – DST (Design Simulation Technologies, Inc.; www.design-simulation.com), today announced the availability of token-based licensing for its flagship commercial products, Working Model 2D and SimWise 4D. The new option ties licensing to actual days of use rather than to a fixed annual subscription or a one-time perpetual purchase, and rounds out DST’s existing portfolio of perpetual licenses and annual subscriptions.

Working Model 2D and SimWise 4D are used every day by engineering firms worldwide to simulate the dynamic behavior of mechanical systems, evaluate design alternatives, and validate performance without the time and expense of physical prototypes. As simulation has become a standard part of the engineering workflow, more people across an organization need access to it — not only the full-time analysts who keep a seat in constant use, but the design engineers, project teams, and specialists who turn to simulation at specific points in a project. Token licensing is built for that second group, extending DST’s tools to occasional and project-based users at a cost that tracks their actual usage.

How Token Licensing Works

Under the token model, a customer purchases a pool of tokens that is drawn down each day the software is actively used. Working Model 2D consumes one token per active day; SimWise 4D consumes three tokens per active day. Tokens remain valid for 24 months from the date of purchase, allowing customers to align license consumption with project schedules rather than fixed calendar subscriptions. Working Model 2D and SimWise 4D both draw from the same pool of tokens, so customers running both products manage a single license investment rather than two separate allocations. Tokens are licensed on a single-machine basis; multi-machine sharing is planned for a future release.

"Our heaviest users keep simulation open all day, and a perpetual or annual license is exactly right for them," said Alan Wegienka, president of Design Simulation Technologies. "But there is a much larger group of engineers who need these same tools at particular moments in a project — to check a mechanism, validate a load case, or settle a design question — and then move on. Token licensing is for them. It lets a firm put professional-grade simulation in front of everyone who could benefit from it, with each person drawing a token only on the days they actually use it."

Online Purchase and Carryforward

Tokens can be purchased online directly from DST in a single transaction, with no purchase order process or quote cycle required. Unused capacity carries forward against future project demand for the full 24-month term, so customers who finish a project with tokens remaining can apply the balance to their next engagement rather than repurchasing capacity they already hold.

Availability

Token licensing is available immediately for commercial customers, alongside DST’s existing perpetual and annual license offerings. Educational customers will continue to be served by DST’s existing academic licensing programs. Prospective customers can compare licensing options and estimate token requirements for their projected usage using DST’s interactive licensing calculator, then purchase tokens online or contact DST sales directly for a needs assessment.

About DST

DST develops physics-based simulation software. The company's products are used by engineering professionals to build and test virtual models of their mechanical designs, and by STEM educators and students in the classroom to teach and learn about physics and engineering kinematics, dynamics, and machine design.

With DST's SimWise 4D, Working Model 2D, and Dynamic Designer products, users evaluate design performance by conducting complete, accurate simulations. Engineers, professors, and students can quickly perform “what-if” analyses, find and correct design problems, plus refine and validate designs without the need for physical prototypes.

Students in high school and college use Interactive Physics, DST's award-winning educational software, to explore and understand the physical world through simulation.

DST develops, markets, and supports these software tools for commercial and academic users worldwide. Selected DST products are available from leading CAD suppliers and CAE resellers. Learn more by visiting the DST website at www.design-simulation.com.
