Full integration with the RFLP approach:

This approach provides a comprehensive and collaborative way to develop a system across its different views. These views go from Requirements (customer needs, compliance demands, ..), to Functional (breakdown of the system into targeted services), to Logical (corresponding technological solutions), up to Physical (implementation) design. The DBM workbench is part of the Logical layer, enabling to define and simulate the behavior of the different technological sub-systems.

Multidisciplinary approach:

Thanks to Dymola, the DBM workbench can handle various disciplines: mechanical, thermal and electrical including electronics. The user can define models based on mixed physics, and see the accurate effects of multiple physics on his system or product.

Availability of ready-to-use model libraries: DBM includes natively an extensive library suited for mechanical (1D/3D), electrical (analog, digital, machines), thermal, fluid, or control systems.

Object-oriented Modeling: The logical breakdown of the system is based on formal components, that represent an electrical resistance, a pump or a gear for instance. This components structure allows concurrent engineering & reuse, increasing development speed & quality. Besides, models can be shared easily across project teams with an efficient traceability.

Uses MODELICA Language for Reuse

Moreover, the open architecture and the powerful MODELICA language allow the designer to develop his own new libraries and to re-use his components in later designs.

Equation based open architecture :

Unlike diagram blocks, where the behavior of each component has to be coupled to its previous components with links oriented in a specific direction, the architecture based on equations enables the components to interact together synchroneously with back & forth influences. Links between them have no direction. With this highly scalable solution, the system architect does not need to restructure his diagram for every small model change. Furthermore, the powerful symbolic solver helps to define large and complex physical systems, such as the gearbox, the shift control, the hybrid electric drivetrain of a vehicle. In addition, their simulation can include many simultaneous events.

Easy and intuitive user interface:

The logical models are built by dragging and dropping components from libraries and arranging them as in a schematic drawing. Every component has a unique icon which makes the diagrams intuitive to the engineer. This modelling approach allows any engineer to model a system, to study its parameter sensitivities, to test design alternatives and to optimize the product performance. It reduces the model development time and eases the day-to-day engineering analysis.
