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 Vehicle System Modeling and Analysis (VeSyMA)VeSyMA Engines and VeSyMA 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.

Detailed vehicle behavior and handling on user-defined road surfaces are modeled with the VeSyMA Suspensions library, which also allows real-time simulation for driver-in-the-loop applications.

Engine and battery cooling is supported by the Cooling library, which can be combined with the Thermal Systems and HVAC libraries. The Human Comfort and Fluid Dynamics libraries adds models of occupant comfort for complete vehicle thermal modeling. Actuator and controller components are available in the Fluid Power and Pneumatic Systems libraries and 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. A wide range of thermo-fluid systems can be modeled with the Thermal Systems library. The Human Comfort Library provides additional models of occupant comfort for cabin thermal modeling.

The Aviation Systems Library models propulsion and aerodynamics of aircraft, both fixed wing and rotary wing, and is designed to connect easily to other libraries. 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 Fluid Power, Brushless DC Drives and Electrified Powertrains libraries. Flexible beams and modal bodies from Finite Element models are managed by the Flexible Bodies library.

The Electric Power Systems library supports modeling of electrical aircraft systems, including generation, conversion and control of high frequency A/C systems.

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.
