What is the Autodesk Fusion Simulation Extension?
The Autodesk Fusion Simulation Extension empowers your team to analyze part performance, manufacturability, and generative design capabilities.
Generative design outcomes can help you discover weight reduction and performance enhancements. Combine this with simulation study types like structural, thermal, and explicit simulations, as well as injection molding to gain a comprehensive understanding of how your 3D design will perform under real-life conditions before manufacturing.

"We [simulated] maybe 100 different iterations over 6 months. If I was to do that by hand in the real world, it would’ve taken me months and cost a small fortune."
—Stu Bowen, Circular Designer and Founder, Lamina Flow
"[Fusion Generative Design] created something that was very interesting and aesthetically pleasing that perhaps we wouldn't have created if we'd have done this from a traditional design method."
—Matt Hill, founder and CEO, Evolve
"There were enough tools for the mechanical design engineers to do what we needed to do, such as simulating mechanisms and designing all the gearboxes and linkages, [and Fusion] also still had the right tools for the product designers."
—Carl Budd, Engineering Manager, Moose Toys

Autodesk Fusion Simulation Extension frequently asked questions (FAQs)
The Fusion Simulation Extension is designed for product development because it gives teams the tools they need to validate performance, reliability, and manufacturability early in the design process. By simulating real‑world conditions digitally, teams can reduce physical prototyping, identify design issues sooner, and iterate faster within the same CAD environment used for modelling and manufacturing preparation.
The Fusion Simulation Extension is intended for product designers and mechanical engineers who need deeper insight into how designs will perform under real-world conditions. It supports both newer users, through guided workflows such as injection moulding, and experienced analysts who require advanced finite element analysis (FEA) capabilities.
AI is used in the Autodesk Fusion Simulation Extension to assist with design exploration, and optimisation through generative design (US Site) technologies. AI‑driven processes help evaluate multiple design outcomes against performance criteria, supporting faster decision‑making and more efficient validation during product development.
The cost of the Fusion Simulation Extension depends on the subscription term selected. Autodesk offers monthly and annual subscription options, with pricing shown in local currency at the time of purchase. See pricing options here.
Yes. The Fusion Simulation Extension requires an active Autodesk Fusion subscription. The extension works as an add‑on that unlocks additional simulation capabilities within Fusion and cannot be used as a standalone product. If you do not currently have an active Fusion subscription, consider Fusion for Design to bundle and save. See pricing options here.
The Fusion Simulation Extension includes a range of advanced simulation study types, such as:
- Nonlinear static stress
- Structural buckling
- Modal frequencies
- Thermal and thermal stress
- Event simulation (quasistatic and dynamic)
- Injection moulding simulation
These studies help evaluate mechanical behaviour, thermal performance, vibration, and manufacturability directly within Fusion.
Yes, the Fusion Simulation Extension incudes generative design (US Site) capabilities to help evaluate and validate AI‑generated design outcomes against real‑world performance criteria.
Unlike stand‑alone simulation software, the Fusion Simulation Extension is fully integrated into Autodesk Fusion, allowing users to move seamlessly from design to simulation to manufacturing without exporting models or managing disconnected tools. This integration supports faster iteration, easier data management, and closer alignment between design intent and simulation results.
Compared to Autodesk Fusion alone, the Fusion Simulation Extension adds access to advanced simulation study types and unlimited cloud‑based solving for those studies during the subscription term. These capabilities go beyond the standard simulation tools included with a base Fusion subscription. Try for free today.
The Fusion Simulation Extension is priced as a subscription‑based extension, available on a monthly or annual basis. During the subscription period, users can run included simulation studies without paying per‑solve cloud token fees, providing predictable costs for frequent simulation use.
Yes. If you already own a Fusion subscription, Autodesk offers free 14-day trial that includes all capabilities included in the Fusion Simulation Extension, allowing users to explore its simulation capabilities and determine whether it fits their workflow before purchasing a subscription. If you do not have an existing Fusion subscription, download a free 30-day trial to explore all features Fusion has to offer.
Yes. The Fusion Simulation Extension has the same capabilities and now also includes the former Fusion Generative Design Extension features.
Yes, subscriptions include unlimited cloud solves for generative design, FEA, electronics cooling, injection moulding, and more. See pricing options here.
