Modelica Libraries


Bibliothèque PowerTrain

The PowerTrain Library includes both basic and sophisticated components for modelling power trains. It can be used to study the dynamics of transition of the shift of an automatic transmission or fuel consumption forecasts during a driving cycle. This library is ideal for real time HIL simulations./span>

It comprises transmissions, continuously variable transmissions (CVT), clutches, conductive patterns and vehicle resistance and control units.



Flexible Bodies Library

The library contains Modelica models of flexible objects such as beams, annular plates with optional thermoelastic properties and modal bodies from a finite element model (FE).

The user can set beam type structures like rotor blades by simply setting an analytical model for a straight and uniform beam which accounts for deformations related to bending, twisting and elongation in two dimensions.

A similar approach is used to model the behavior in bending of annular plates such as a helicopter swashplate. It also supports the slide-on-plate nodes that facilitate the modelling of contact slippage problems.



Hydraulics Library

The Hydraulics library is a tool that is both powerful and easy to use for modelling hydraulic systems using oil.

Applications include machine tools, automatic transmissions and open and closed loop controls, used for example for excavators and forklifts.



Pneumatics Library

The Pneumatics Library (tyre) includes basic model classes for modelling cylinders and motors, valves and nozzles, concentrated volumes, circuits and sensors.



Smart Electric Drives Library

The Smart Electric Drives Library allows the user to model and simulate a complete electric drive system, an ideal tool for the simulation of hybrid vehicles and new alternative concepts with electrical auxiliaries..



Vehicle Dynamics Library

The VehicleDynamics library (Vehicle Dynamic) is used to simulate the dynamic behavior of a vehicle and its stability. It contains components such as tyres, driver models, shock absorbers, wishbones, anti-roll bar suspensions, but also front and rear complete suspension systems (MacPherson, double wishbone, multi arms…).



Electric Power Library

This provides a framework for the simulation and analysis of electrical systems for static and transient operations. The user can model the entire plant from the energy source (oil, gas, hydro and other sources of energy such as wind) to the generator, to the network and even to the consumer.



Engine Dynamics Library

Used for modelling, simulation and analysis of engine systems, including gas exchange. It is ideally suited to represent intermediate response engines and the corresponding commands.

Among its applications are the design of controls to reduce transient engine emissions, modelling of transient exhaust for optimum operation of post-treatment of exhaust systems and engine response dynamics.



Hydro Power Library

Provides a framework for modelling and simulating the operation of a hydroelectric plant. It allows analysis and performance optimization, e.g. for central tanks and/or multiple turbines to maximize overall efficiency.
Planning for testing and commissioning procedures can be organized, reducing the risk of unexpected events and limiting costly tests at the actual center.



Thermal Power Library

Provides a framework for modelling the operation of thermal power plants, including transitional operations. Different designs of plants and their dynamic behavior can be studied at conceptual studies stages.

One of the strengths of this library is its ability to simulate static or dynamic behavior, using the same model.



Liquid Cooling Library

Intended for the design of liquid cooling systems with compressible or incompressible flows. Among its applications are engine cooling, thermal management of the batteries and the electronic cooling of power and machines in the automotive, industrial equipment and processing sectors.



Air Conditioning Library

Intended for the design, analysis and optimization of vehicle air conditioning systems. This library includes all components for refrigeration and cooling cycles using typical refrigerant fluids such as R134a or even CO2. It is also suitable for two-phase flow and air management for all phases of design up to implementation of the control system.
