The quality of a system model depends on how faithfully reality is represented. It's not about achieving the highest accuracy (as higher accuracy often means slower, more error-prone, and harder to interpret), but rather about capturing the physically and technically relevant aspects for the specific use case. This step requires a lot of experience.
The Competence Center for Fluid Mechanics and Numerical Methods has over 20 years of experience in modeling physical systems and processes. The journey of System Modeling began with Organic Rankine Cycle (ORC) systems. Today, the research group in System Modeling, Digital Twins creates digital models and twins for various applications, from flow and energy systems to mechanical systems and medical technology applications. In this process, the modeling language Modelica™ is utilized to develop and apply dynamic system models.
