Letter from the Board

 

Dear Modelica Interested,

The 10th International Modelica Conference took place in March 2014 in Lund, Sweden. The conference was a great success and about 400 participants enjoyed the many presentations on Modelica, FMI, the large exhibition and discussions between the participants. As always, the conference proceedings are freely available from Linköping University Press. The next, 11th Modelica Conference is now planned to take place in September 2015 at "Le Palais des Congrès de Versailles" (close to Paris and directly in front of the famous Palace of Versailles). The exact date will be fixed soon. It will be organized by Dassault Systèmes (local organizer), by Linköping University (scientific program) and by the Modelica Association.

The FMI 2.0 Release Candidate 1 was released in 2013. In the meantime about 80 tickets had been reported and fixed in the specification draft. This improved draft was the basis of a FMI Plug-Fest in Berlin, organized by QTronic two weeks ago. Most of the tool vendors currently working on prototype implementations for FMI 2.0 met and evaluated the compatibility of their prototypes and of the latest version of the specification draft. For more information see below.

If you have interesting news for the Modelica community, please contact the newsletter editor (Michael Tiller) for information on how to submit newsletter articles for possible inclusion in the next newsletter. The deadline for articles for the next newsletter is September 15, 2014.

Best wishes from:

Martin Otter (Chairman of the Modelica Association)

10th Modelica Conference


 
10th Modelica Conference

As already mentioned in the letter from the board, the 10th Modelica conference was a great success, and demonstrated that the use of Modelica and FMI is quickly expanding. A clear indicator of the growth was the number of contributions: 50% more than for the previous conference. While contributions from the automotive industry where as strong as ever, some engineering domains grew even more:

  • The rapid adoption, and continued evolution of the FMI standard resulted in a very well attended tutorial, and a number of interesting sessions. This is a continued trend over several conferences.
  • Two sessions dedicated to aerospace applications showed that the promotion of Modelica in a number of EU Clean Sky calls has spawned interesting research, and first results were presented.
  • The IEA ECB (Energy in Buildings and Communities) annex 60 Programme has a strong focus on Modelica and FMI and has resulted in a number of contributions from the buildings research community.
  • There is a trend of broadening the use of Modelica models, e.g. for fault handling and analysis, early concept design of systems, and optimal system operation after commissioning (MODRIO project)

As always, the conference participants constituted a healthy mix of industry practitioners, tool vendors and researchers. The community is growing, a large number of new companies and institutions came for the first time to a Modelica conference, and the participant numbers indicate that Modelica is growing regionally in the USA and Asia now.

Overall, the growth of Modelica and FMI seems to have accelerated in the recent past, and the Modelica Association is optimistic about the continued growth of strong standards for systems modeling and simulation.

FMI 2.0 Pre-Release Plug-Fest


 

On May 12th and 13th, 14 programmers who are responsible for FMI functionality from 8 FMI-supporting companies (Dassault Systèmes Lund, dSPACE, IFPEN, ITI, MapleSoft, Modelon, QTronic, Siemens (LMS)) met in Berlin for the "FMI 2.0 Pre-Release Plug-Fest".

In those two days, a useful network of personal contacts was established between different vendors to directly resolve compatibility issues in the future. During this meeting, many improvements where made to both import and export support across tools. A number of small issues where discovered in the specification and logged in the FMI issue tracker. No major issue was found that would derail the current release plan for FMI 2.0. Many Test-FMUs and CrossCheck results where created and uploaded to focus further development.

The Plug-Fest participants propose to the FMI Steering Committee to:

  • release FMI 2.0 after the remaining issues have been resolved and to
  • approve small changes to the CrossCheck Rules proposed by the group.

Given the productivity of such personal meetings the community should adopt the "PlugFest" format as an integral part of the development process for future FMI releases!

Free Interactive Book: Modelica by Example


 
Free Interactive Book: Modelica by Example

Xogeny is proud to announce the release of "Modelica by Example", a new book on Modelica by Dr. Michael Tiller. A free interactive version of the book is available online now.

The goal in producing this freely available book is to make it easy for anyone, anywhere to learn Modelica through a series of easy to understand examples. The book starts with the basics of representing mathematical behavior and then gradually demonstrates how the features in Modelica allow this behavior to be captured in reusable components, subsystems and architectures.

The HTML version of the book offers readers the chance to interact with the examples. Nearly every figure presented in the book showing the response of an example model also features an "interactive" option that allows readers to modify parameter values and then re-simulate the system response directly in their browser.

The book is currently released in an "Early Access" version. The purpose of this release is to collect feedback on the book from the community with the goal of making improvements prior to publication of a print edition of the book.

Electronic versions of the book in both ePub and PDF format for offline use can also be purchased from the book homepage.

The Vapor Cycle Library is a Modelica model library for the design of vapor cycle systems, including vapor compression cycles for heating or cooling purposes. Component interaction and dynamic system behavior can be studied at an early design stage.

The library can be used as an integrated part of energy management design for both mobile and residential applications, by combining it with e.g. Liquid Cooling Library, Heat Exchanger Library and other Modelica libraries that cover mechanical and electrical parts of the system such as Electric Power Library.

The latest release of the vapor-cycle library contains a number of exciting features, in particular an interface to the NIST REFPROP fluid property data base.

The following new components and features have been added:

  • A pump model with several different options for defining flow and power characteristics
  • A turbine model with flow rate determined according to the Stodola law and a given nominal operating point
  • A fluid flow source that allows to evaluate the effect of charge in a closed cycle on system performance, and add or remove charge in a running simulation
  • Automatic aggregation of working fluid volume and mass in a system
  • An interface to the NIST REFPROP data base. Any single-component fluid from REFPROP can be included easily in the drop-down list for possible working fluids
  • Computational speed in fluid property functions has been increased by a factor two
  • Temperature is introduced as an alternative input to specific enthalpy in working fluid sources and sinks

The new Vehicle Dynamics 1.9 Adds Support for Delft-Tyre and Standard Tyre Interface Tire Models


 
The new Vehicle Dynamics 1.9 Adds Support for Delft-Tyre and Standard Tyre Interface Tire Models

The Vehicle Dynamics Library is a Modelica model library for modeling and simulation of vehicle dynamics, including chassis and powertrain. It provides an open and user-extensible environment for full vehicle and subsystem analysis. Designed with a hierarchical structure and an extensive library of predefined vehicle components and templates, the configuration of any class of wheeled vehicles is convenient and straight-forward. Vehicle Dynamics Library allows you to optimize and verify design of your vehicle systems from the early design phases through control design and implementation. Vehicle Dynamics Library is unique in that it provides true multi-body, multi-domain simulation with real-time performance and model export capabilities to allow distribution across your organization.

The Vehicle Dynamics Library has been extended to include support for the industry standard Delft-Tyre product line of TNO, which includes MF-Tyre ® and MF-Swift ® tire force models.

MF-Tyre is the Delft-Tyre standard implementation of the renowned Pacejka Magic Formula, with validated steady-state and transient behavior up to 8Hz, making it the ideal tire model for handling and control prototyping analyses.

The Delft-Tyre wheel model fully supports our Vehicle Dynamics Library’s built-in ground models, TNO road property files, and OpenCRG road descriptions.

The Standard Tyre Interface (STI) was developed in 1997 by the TYDEX workshop to define a standard interface between vehicle, tire and road models. This standardized interface makes it possible to switch between different tire models without the need to modify the vehicle or road models.

By supporting the STI, our Vehicle Dynamics Library enables you now to quickly add 3rd party tire models that adhere to this standardized interface.

Efficient Integration of Different Modeling Approaches - dSPACE supports the FMI Interface


 
Efficient Integration of Different Modeling Approaches - dSPACE supports the FMI Interface

dSPACE is the world’s leading provider of solutions for developing ECU software and mechatronic controls. With a history of over 25 years, dSPACE products provide solutions throughout the development cycle for applications in a wide range of industries.

As an open standard, the Functional Mock-up Interface (FMI) simplifies the use of best-in-class tools for specific modeling tasks and the consistent reuse of models in different development phases and departments. dSPACE now supports FMI on its PC-based virtual validation platform VEOS® and on its real-time simulation platform SCALEXIO® in addition to the support of MATLAB/Simulink®-based simulation models. Functional mock-up units (FMUs) can be integrated in comprehensive MIL/SIL/HIL projects together with virtual ECUs (V-ECUs) and Simulink models. The user workflow for importing and connecting these FMUs to other model interfaces and to simulator I/O is identical to the user-friendly workflow for V-ECUs and Simulink models. Different modeling approaches (e.g., based on physical modeling with Modelica) can therefore be integrated into new or existing MIL/SIL/HIL projects quickly and efficiently.

dSPACE ensures smooth interfacing between all the tools in the dSPACE tool chain for virtual validation and HIL projects to provide consistent simulation and parameter access throughout the different development phases. This means you can reuse not only the models based on FMI, but also corresponding tests and experiments based on tools such as AutomationDesk® and ControlDesk® Next Generation or other XIL API-compatible tools. This completes the FMI reusability approach for virtual validation and HIL use cases.

Highlights of dSPACE FMI support:

  • FMI support provided with VEOS (MIL/SIL use cases) and SCALEXIO (HIL use cases)
  • Consistent interfaces and variable access for the seamless reuse of models, tests, experiment layouts and data throughout the different development phases

LMS Imagine.Lab AMESim Provides Heterogeneous Simulation Platform with Modelica


 
LMS Imagine.Lab AMESim Provides Heterogeneous Simulation Platform with Modelica

LMS Imagine.Lab AMESim Rev13 provides an excellent platform for heterogenous simulation. Users benefit from two key values: access to pre-existing libraries of comprehensive, validated, domain-specific models, and the ability to create custom libraries using a full-featured Modelica development environment. Assembled models are compiled and executed to take full advantage of a powerful set of analysis tools for visualization, linear analysis and design exploration.

AMESim Rev13 SL2 will be released in May 2014. This service level release includes a streamlined Modelica modeling workflow and improved statechart environment. The statechart environment is an AMESim-integrated graphical definition, simulation and analysis environment for control and operating logic. It is based on the Harel Finite State Machine theory, using clear and robust language semantics based on Modelica. The statechart environment is designed to provide an easy-to-use graphical environment to define statecharts, validate them, simulate them, and analyze results in a way that is very similar to the methods used in other AMESim analysis tools (such as plots or dashboards).

Our team enjoyed many interesting discussions at our exhibitor booth and vendor session during the 10th International Modelica Conference. If you weren't able to attend our presentations, you can still find our papers in the Modelica Publications page:

LMS Imagine.Lab AMESim Empowers Model-Based Collaborative Design with FMI


 
LMS Imagine.Lab AMESim Empowers Model-Based Collaborative Design with FMI

LMS Imagine.Lab AMESim Rev13 covers the complete range of the FMI specification, confirming its position as a powerful and open platform for 1D multi-domain system simulation, aimed at supporting Model-Based Collaborative Design at all steps of product development.

Embedded Know-how

With AMESim co-simulation FMUs, benefiting from high detail physical models and from AMESim’s native best-adapted solver becomes possible in any FMI-compliant target environment. All these powerful solver capabilities are embedded and can be modified from the importing tool. This maximizes the reliability of the results, protects against potential effects of software version changes, and allows even non-expert users to easily plug AMESim technology into their existing software environment.

IP Protection

Given the importance of customer-supplier relationships in automotive and aircraft industries, the exposed parameters and variables of an AMESim FMU can be completely fine-tuned. Thus model designers can safely select the confidentiality level they want—from “white-box” FMUs to “black-box” FMUs—while distributing their models, which is a strong requirement of Model-Based Collaborative Design.

Heterogeneous simulation platform for system-level analysis

Thanks to its capability to import multiple Model Exchange or Co-Simulation FMUs, AMESim can easily couple together multidisciplinary subsystems coming from various specialized codes. AMESim users can therefore predict and analyze the performance of their complete product at the system-level.

Siemens PLM Software, as active member of the FMI initiative, promotes the use and the development of the Functional Mock-up Interface as a standard tool to support real-world Model-Based Collaborative Design and continues developing products that serve the needs of its industrial customers.

Online Modelica Syntax Checker from Maplesoft


 

Many modeling tools, including MapleSim, support the Modelica standard so that model and component definitions can be developed in one system and then used in another. To ensure maximum compatibility with other tools, it is important that the Modelica code adheres strictly to the Modelica language definition. Maplesoft has developed a Modelica syntax checker to test code against different versions of the standard language definitions to ensure that it is syntactically correct.

Although originally written for use inside MapleSim, Maplesoft realized that this tool could be useful to users of other Modelica-based modeling tools, and so decided to make it freely available to the community. If you are having trouble importing a Modelica file from one system to another, you can use this online tool to check the syntax of your code and to determine where changes need to be made if it the code is not syntactically correct.

You will find the Modelica Syntax Checker at www.maplesoft.com/modelicasyntaxchecker.
