Integrating Multiple Engineering Disciplines

Modelica tools are domain-agnostic, meaning that they process equations in order to generate efficient simulation code. Domain knowledge is packed in Modelica libraries, designed to handle a variety of applications from mechanical, electrical, and thermo-fluid domains.

The libraries can be used with both Dymola and 3DEXPERIENCE Dymola Behavior Modeling, either on their own or with other Modelica libraries, to model and simulate complex systems that can span multiple engineering disciplines.


Automotive applications span three categories:

- Engine and drive train modeling with VeSyMA libraries.
- Hybrid/alternative drivetrains with Battery, DC Drives, Electrified Powertrains.
- Detailed vehicle behavior with VeSyMA Suspensions. Cooling, Thermal Systems, HVAC, Human Comfort, and Fluid Power support. Hierarchical Modelica models for flexibility and component reuse.

The hierarchically structured, open-source, Modelica models offer unprecedented flexibility for multiple vehicle configurations while reusing common components.

Aerospace and Defense

Libraries like Thermal Systems, Human Comfort, Flight Dynamics, Fluid Power, Brushless DC Drives, and Electrified Powertrains empower complex aircraft modeling.

Thermal Systems handles diverse thermo-fluid systems, while Human Comfort enhances cabin thermal modeling. Aviation Systems connects propulsion and aerodynamics, while Flight Dynamics swiftly analyzes flight characteristics. Actuators employ Fluid PowerBrushless DC Drives, and Electrified Powertrains. Flexible Bodies manages modal bodies. Electric Power Systems models electrical aircraft systems, from generation to control.

Energy, Process and Utilities

Ever more stringent requirements on environmental impact drive the trend towards more detailed modeling of physics and control systems. The Industrial Process Simulation library is used for modeling paper&pulp + steam networks. Application to industrial plants yield benefits, such as, correct design of modified and new plants, controller tuning and optimization, and reduced commissioning time. The ClaRa Plus library facilitates simulation of e.g. advanced combined cycle power plants.

The Heat, Ventilation and Air Conditioning (HVAC) library allows you to minimize building HVAC operating costs by selecting the correct system control strategy and avoid costly HVAC system design errors early in the building design process. The Human Comfort library provides an integrated approach to simulate the thermal comfort within an occupied building or vehicle.

Industrial Equipment

All kinds of industrial equipment can be modeled using the mechanical libraries of the Modelica Standard Library, including 3D multi-body systems. Other options are flexible beams and modal bodies originating from a Finite Element model. Actuators and control systems are modeled with the Fluid Power, Pneumatic Systems, Brushless DC Drives and Electrified Powertrains libraries. The thermal properties of industrial machinery are easily modeled with the Thermal Systems and Cooling libraries.
