Industry Solutions - Modelica Libraries

Developed by domain specialists, these libraries are used in conjunction with Dymola or 3DEXPERIENCE Dymola Behavior Modeling to quickly and easily model and simulate the behavior of complex systems that span multiple engineering disciplines.

Integrate 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.


The automotive applications fall into three main categories. The engine and drive train are modeled using the Engines and Powertrain libraries. The flexibility of the open Modelica language is particularly suitable for modeling hybrid or alternative drive trains using the Battery, Brushless DC Drives and Electrified Powertrains libraries. Modal bodies or flexible shafts are available through the Flexible Bodies library. Engine and battery cooling is supported by the Cooling library, which can be combined with the HVAC library. The Human Comfort library adds models of occupant comfort for complete vehicle thermal modeling. Controller components are available in the Modelica Standard Library.

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

Aerospace and Defense

A multitude of libraries offer the capacity to model the complex thermo-fluid systems of aircraft, ranging from fuel systems to environmental control. The Human Comfort Library provides additional models of occupant comfort for cabin thermal modeling.

The Flight Dynamics library enables the rapid modeling, simulation and analysis of the flight dynamic characteristics of a wide range of aircraft and UAVs. Actuators for flight control and other subsystems use the Brushless DC Drives and Electrified Powertrains libraries. Flexible beams and modal bodies from Finite Element models are managed by the Flexible Bodies library.

Energy, Process and Utilities

Ever more stringent requirements on environmental impact drive the trend towards more detailed modeling of physics and control systems.

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 Brushless DC Drives and Electrified Powertrains libraries. The thermal properties of industrial machinery are easily modeled with the Cooling library.
