Dynasim Offers Preview of Dymola 5.0 Software, its New Dynamic Laboratory, with Unique Features for Multi-Engineering Modeling and Simulation

Lund, Sweden (ots) - Dymola Reduces Time to Market and Production Costs of Autos and other Dynamic Systems Dynasim AB (www.dynasim.se), the leading company for multi-engineering modeling and simulation software is providing an early look at its Dymola 5.0 software that will debut at the SAE 2002 World Conference in early March. The new generation of the program features important enhancements like collaborative team modeling abilities, an improved graphical user interface, the latest in the dynamic modeling language Modelica, simplified model building and automated code generation. All capabilities are targeted toward further enhancing automotive engineering developer productivity, lower design costs and reducing the product's time to market. "Dymola 5.0 allows simulation of detailed models of complete vehicles including engine, transmission and chassis prior to committing to prototypes and full production." said Dr. Hilding Elmqvist, Dynasim's CEO. "Dymola is unique in allowing modeling and simulating the multiple engineering disciplines of mechanics, electronics, thermodynamics, chemistry, hydraulics and control systems utilized in a car." Elmqvist added. "This enables analysis of vehicle acceleration, shift quality, fuel economy, emissions, noise and even new technologies like fuel cells and hybrid electric car systems." About Dymola 5.0 The new Dymola 5.0 features: New graphical user interface for large-scale collaborative modeling. Emphasis has been put on both simplifying the task of building models for the novice user and providing tools for building and managing large and complex models developed by a collaborating team of engineers. With more than one thousand Modelica model components available, the package browser of Dymola 5.0 helps the user find the appropriate components and view their HTML-based documentation. New models are built by dragging-and-dropping and connecting models in a model composition diagram. Dymola 5.0 has a built-in graphical editor for designing icons and for making graphical annotations of models. Bitmaps and vector graphics can be imported from other tools like PowerPoint and Visio. It is even possible to import 3D graphic shapes and mass properties of mechanical bodies from CAD packages. Support for the latest Modelica modeling language version 2.0. Developed by the non-profit Modelica Association, the object-oriented modeling language Modelica is designed to allow convenient, component-oriented modeling of complex physical systems containing, for example, mechanical, electrical, electronic, hydraulic, thermal, control, electric power or process-oriented subcomponents. A large set of libraries of fundamental models described by differential, algebraic and discrete equations are available. Improved language constructs for giving initial conditions is one major feature of the Modelica 2.0 specification. New algorithms for even faster simulations. Dymola 5.0 employs new algorithms for automatically generating the code, based on the user's model, which is needed for efficient simulation. This has given a break-through, enabling simulation at the speed of sound for hydraulic systems. Real-time, hardware-in-the-loop simulation (HILS) of, for example, the shock waves in hydraulic breaking systems is now possible. The C-code that Dymola 5.0 generates can be exported to Simulink and dedicated HILS systems. During the design phase, hundreds or thousands of simulations are performed with different parameter sets. These new code generation algorithms drastically reduces waiting time for design engineers. It is even possible to let Dymola 5.0 use many computers and automatically schedule the simulations in parallel to reduce the design cycle even more. Extended simulation and post-processing facilities for shortening design cycles. Dymola 5.0 has powerful features for post-processing of simulation results, which allows browsing of hundreds of thousands of variables and comparison with experimental data. Data can be imported and exported to other programs like Matlab and Microsoft Excel. There is a scripting language for automating design studies and analysis. Automatic logging of design sessions including graphics is provided as HTML code for archiving and sharing over the Internet. Animation in 2D or 3D of dynamic behavior can be performed even during real-time simulation, thereby enabling users in the simulation loop. 3D animations can be exported as VRML code to the Internet. WebEx Demonstration Previews Available Previews of Dymola 5.0 are available for journalists and analysts prior its final release via an online WebEx session with Dynasim CEO Dr. Hilding Elmqvist. To set up an online briefing and demonstration, interested parties can call +1/212/651-4215 or send an email to joseph.dans@fusionpr.com About Dynasim AB Dynasim of Lund, Sweden (www.dynasim.se) was founded in 1992 and its mission is to develop and market the software tools that industry needs for solving demanding modeling, simulation and design problems. Its exceptional executive staff and core development team are composed of well-known scientists in the Multi-Engineering Modeling and Simulation field. The program Dymola utilizes an object-oriented modeling methodology pioneered by the founder and CEO, Dr. Elmqvist. Dynasim is the technology leader for complex large-scale modeling and simulation. The company has developed a new technology for multi-engineering modeling and simulation, Dymola, which is needed within automotive, aerospace, robotics and process applications. Dymola allows simulation of the dynamic behavior and complex interactions between mechanical, electrical, thermodynamic, hydraulic and control systems. The industrial users can therefore avoid building physical prototypes and thus reducing the overall design costs and the time to market. Dymola's modeling and simulation capabilities enable users to solve their demanding multi-engineering design challenges effectively since Dymola allows designers to reuse ready-made model libraries, which increases productivity and because collaborative model development is promoted. Furthermore, Dymola automates the manipulation of model equations and uses drag and drop techniques that simplify the design process even for novice developers. All this means that more design cases can be investigated to give safer, more fuel-efficient products with reduced emissions, helping companies comply with environmental laws. Dynasim is well positioned since the technology is mature and Dymola is already used by hundreds of engineers at Toyota, Ford, BMW, German Aerospace Center and other leading international companies like United Technologies. Early adopters are present in many companies who promotes Dymola by gives internal seminars and courses on Dymola. More than one hundred universities including top ones like Caltec, RPI and the University of Michigan use Dymola to train their engineering design students. Dymola has been used in the design of products already available on the market, for example, the hybrid electric car Prius from Toyota. The validation of the coordinated computer control system by use of Dymola was a success because no essential changes were needed in the prototypes or after the car was marketed. The next generation of the software, Dymola 5.0, is just about to start shipping, a sales organization is available not only in Europe and Japan but now also in the U.S.A. and public relations have started. ots Originaltext: Dynasim AB Internet: www.newsaktuell.ch Contact: Dynasim AB Joseph Dans Director of Accounts Fusion Public Relations 570 Seventh Avenue New York, NY 10018 Tel. +1/212/651-4215 E-Mail: joseph.dans@fusionpr.com
