Honeywell’s UniSim Design Suite is an intuitive process modeling software that helps engineers create steady-state and dynamic models for plant design, performance monitoring, troubleshooting, business planning, and asset management.

The process simulation market is under transformation. Triggered by technological advancements and new customer requirements, process simulation models, which have traditionally been desktop analysis and decision-making tools, are now leveraged into new high-value solutions, such as “connected” operational monitoring.


UniSim Design accurately calculates physical, transport, separation, and reaction kinetic properties. Market-leading, it’s field-proven to give realistic results in both steady-state and dynamic environments.

Users can quickly create robust, realistic process simulation models to use for offline and online (digital twin) applications.
