The simulator resource contains the definitions necessary for Cognite Data Fusion (CDF) to interact with a given simulator. It serves as a central contract that allows APIs, UIs, and integrations (connectors) to utilize the same definitions when dealing with a specific simulator.
Each simulator is uniquely identified and can be associated with various file extension types, model types, step fields, and unit quantities. Simulators are essential for managing data flows between CDF and external simulation tools, ensuring consistency and reliability in data handling.
