New releases of Modelon Modelica LibrariesModelon
Modelon is releasing updated and improved versions of its Modelica libraries.
Dymola 2017 from Dassault Systèmes has been recently released and in connection to this Modelon announces new releases of Modelica Libraries.
Air Conditioning Library
Air Conditioning Library 1.12 contains new heat transfer and pressure drop correlations for liquid fluids and overview tables, which guide you in using the right correlations in your heat exchanger.
Environmental Control Library
Environmental Control Library 3.2 contains substantial improvements to simulation performance. In Dymola 2017, it is now possible to simulate system models entirely with analytical Jacobians, leading to faster and more robust results.
Engine Dynamics Library
Engine Dynamics Library 1.2.5 was extended with automatic aggregation of the system volume and mass with focus on enhanced Modelica compliance.
Fuel Cell Library
Fuel Cell Library 1.3.3 adds models for handling fuel and gas mixtures specific to the fuel cell field. The library is extended with two sensor components: one for steam to carbon ratio, and one for oxygen to carbon ratio.
Fuel System Library
Fuel Systems Library 3.2 contains extensions to the user guide and documentation. With this, new and experienced users can work more effectively with the library.
Heat Exchanger Library
Heat Exchanger Library 1.4.1 features new spatial temperature plots and adds improved steady-state initialization capabilities. User friendliness is improved with the capability to modify component mass independently from the entered geometry.
Hydraulics Library 4.4 includes the possibility to scale states for improved numerical accuracy, for instance when linearizing models. Such analyses now give you better information about local stability and frequency response of a system.
A tutorial on how to linearize a common rail diesel injection system model is provided with this release.
Oil property models are now straight forward to parameterize from a standard oil data-sheet. It is also now possible to use ThermoHydraulics with our simplest oil property model when there is just a limited amount of oil data available.
Liquid Cooling Library
Liquid Cooling Library 1.5 makes it possible to visualize the state of important system variables dynamically during simulation.
The component icons received a face lift, component temperatures, liquid levels and valve positions can now be monitored directly in the system diagram layer.
A ball valve model and volumetric flow sensors are now available and a number of enhancements were added to the pump models.
Pneumatics Library 2.0 is a new major release which includes the possibility to account for thermal effects. Thermal effects have substantial impact on the performance and dynamics of a system, and often represent key interactions with other parts of a design.
Additionally, the library provides you with a large set of new primitives and fluids for your models. For instance you can choose from real gases, as well as several new predefined ideal-gas fluids.
Both Hydraulics and Pneumatics include a brand new example model demonstrating FMI- and multi-library capabilities. The example includes a pneumatic brake booster actuating a hydraulic brake system.
Vapor Cycle Library
Vapor Cycle Library 1.3 contains significant improvements in simulation speed for models with two-phase working fluids.
Documentation and tutorials received a quality lift as well.
Vehicle Dynamics Library
Vehicle Dynamics Library 2.3 includes two new independent suspension linkages: four-link and trapezoidal have been introduced.
Each link has a separate attachment point to the upright.
Both suspension linkages have either steerable or non-steerable configurations, as well as kinematic and multiple compliant versions.
A four-link suspension is effectively a double wishbone suspension with either the lower or upper wishbone split into two separate fore/aft links and a steer link.
A trapezoidal suspension has a lower wishbone with a link connected to the upright, a single upper link and a steer link
Support has also been added to perform virtual K&C experiments using the live wheel rig introduced in version 2.1. K&C experiments are now broken into two groups: HubRig and WheelRig depending on which suspension test rig is used.
