Enhancing Multi-Domain System Simulation with FMI Co-Simulation

As systems become increasingly complex across every field of science and engineering, the importance of computer simulation in design, analysis, and verification continues to increase over time. The traditional process in which a system is modeled and simulated in a single tool is called monolithic simulation. On the other… Read More The post Enhancing Multi-Domain System Simulation with FMI Co-S
