SystemsEngineering Tips&Tricks CATIADBM Products are becoming more complex and the demands for better performance and reduced cost are ever increasing. Much of the complexity arises from a higher degree of interaction between sub-systems. Combined with the demand to reduce time-to-market, the need to increase development productivity is higher than ever. With Model Based System Engineering, system architectures can be quickly assessed based on behavior and performance simulation. Informed decisions are made earlier in the development process, long before detailed design or physical prototype manufacturing. CATIA Dymola Behavior Modeling (CATIA DBM) is a Modelica compliant solution that efficiently models and simulates multi-physic dynamic systems. CATIA DBM rapidly solves complex multi-disciplinary systems modeling problems that can contain a combination of mechanical, electrical, electronic, hydraulic, thermal, control, electric power or process-oriented characteristics and components. CATIA Dymola Behavior Modeling Benefits: ·Powerful multi-disciplinary systems engineering through compatible model libraries for a large number of engineering domains. ·High-fidelity modeling of complex integrated systems. ·Intuitive modeling. ·Open model libraries enabling users to easily build their own.
MULTI-DISCIPLINE MODELING AND SIMULATION
The unique cross-discipline support provided by CATIA Dymola Behavior Modeling enables users to define and simulate models that comprise physical components from many engineering domains. The fundamental system components are described by ordinary differential and algebraic equations resulting in reusable models of complete systems that are more easily maintained than traditional block diagram based modeling approaches.
INTUITIVE MODELING
The application’s graphical editor and the multi-discipline engineering libraries make modeling fast and easy. The libraries include elements corresponding to physical devices which are simply dragged-and-dropped to build the system model. Interactions between the components are conveniently described by graphical connections that model the physical coupling of the components. This means that models are intuitively organized the same way as the physical system is composed.
OUTSTANDING PERFORMANCE
CATIA Dymola Behavior Modeling has unique and outstanding performance for solving DAEs. The key to this high performance and robustness is symbolic manipulation that optimizes and solves the systems of equations that define the system.
[Mechanism with three planar kinematic loops and one degree of freedom.]
For example, CATIA Dymola Behavior Modeling will optimize the 3D multi-body mechanism above utilizing constraints given by the joints and evaluated parameters. The non-linear equation systems for the coupled planar loops will be solved analytically during the translation. The generated simulation code has only two continuous time states. These techniques together with special numerical solvers enable real-time Hardware-In-the-Loop simulation of automotive drivelines and full vehicle dynamics models with flexible elements. For certain kinds of models large performance gains can be achieved by using multiple processor cores. The app will automatically analyze the equations and partition the code.
