Corys

Corys is a French company that builds training and engineering simulators. It is based in Grenoble, France. Its simulators serve the power, transport and process industries. The company has supplied them for more than 35 years.

The Power Simulation division builds simulators for nuclear operator training and engineering. These cover nuclear, thermal and hydraulic plants and power networks. The Transport Simulation division makes training simulators for drivers. These cover freight trains, high speed trains, main lines, light rail and tramways, subways and commuter trains. In October 2026 BLS Cargo Nord chose Corys to equip its training teams with driving simulators for cross-border freight operations.

The Process Industries division offers dynamic simulation for process training and engineering. It covers oil and gas production, gas processing, biogas and LNG, refining, petrochemicals, chemicals, fertilizers, water, hydrogen, and batteries and renewables. Corys has also shown a battery cell manufacturing simulator to French and British industry partners.

The company uses dynamic modelling, computer generated images, cloud tools and artificial intelligence. Its simulators rely on engineering grade models, virtual environments, and control room replicas or emulations. Corys says its simulators help customers lower training and engineering costs, build workforce skills and improve safety and efficiency. It builds custom solutions for each project.

Corys is an official Epic Games service partner and builds Unreal Engine environments for fields where results must be validated. It has also received an Epic MegaGrant. The company employs more than 380 engineers and scientists worldwide.

Its head office is in Grenoble. It has subsidiaries in the United States, in Jacksonville and Houston, in India, in Pune, and in Cyprus, in Nicosia.
