CENOS operates on an annual subscription basis, with pricing determined by the features and number of users required. The starting price for an annual subscription is $6,000 USD.

For certain applications, we also provide the option of Project-based subscriptions, which are available for shorter durations of 3 months, catering to specific project needs.

If you’d like a customized quote or further details, feel free to reach out to our sales team.

CENOS primarily provides software that is designed for ease of use, empowering our customers to run their own simulations with confidence. Alongside the software, we offer high-level customer support to ensure a seamless experience.

For customers who require additional assistance, we also offer a Premium Support service. Through this service, our team can collaborate on simulation projects, including running simulations on your behalf to address workload challenges or assist with new designs.

No, the software doesn’t create designs for you. Instead, it acts as a robust simulation platform that helps you test and perfect your own ideas.

This means you can experiment with numerous design variations virtually, ensuring you arrive at the best design without the expense and delays of building physical prototypes.

CENOS simulations are highly accurate, with results closely matching real-world outcomes when the simulation setup mirrors the real-life setup. The precision of your results depends on how well the simulation parameters align with the physical conditions.

All CENOS users, including companies like Volkswagen, John Deere, and ThyssenKrupp, have validated the software’s accuracy through their own tests. You can explore some of these validation studies here.
