The increasing complexity of automotive design requires more frequent and integrated use of simulation for cross-domain development and validation. To support this need Renault has formalized the concept of simulation platform that integrates five key elements: digital vehicle, driver, simulation environment, simulation means, and assessments. The FMI standard facilitates interoperability among these components.
A case study on thermal management highlights challenges with varying co-simulation step sizes, impacting performance and accuracy. Introducing FMU Containers, which embed multiple FMUs and manage their connections, significantly improves simulation efficiency.
