Computational Methods Applied to Modelica Simulation Models in a Web Based Framework

Abstract

In this paper, it is illustrated how computational design methods such as design optimization and probabilistic analysis is applied to system simulation models in a web based framework. Special emphasis is given models defined in the Modelica modeling language. An XML-based information system for representation and management of design data for use together with Modelica models as well as other types of models is proposed. This approach introduces a separation between the model of the system and data related to the design of the product. This is important in order to facilitate the use of computational methods in a generic way. A web based framework for integration of simulation models and computational methods is further illustrated. The framework is based on open standards for distributed computing and enables so-called service oriented architecture. Finally, an example is presented, where design optimization and probabilistic analysis is carried out on a Modelica model of an aircraft actuation system using the proposed and implemented tools and methods.

A web-based, collaborative modeling, simulation, and parallel computing environment for electromechanical systems

“…And computational methods applied to Modelica simulation models in a web-based framework was also studied. 13 Users can complete the experiment through connecting the custom experimental components, and the results of the experiment can be obtained after the simulation. However, all the studies presented were based on the specific purpose and lacked some features that are actually needed in industry and research, such as a general web-based visual graphical editor.…”

“…Finally, standalone platforms do not support parallel computing so that they are inefficient to execute some centralized computing tasks such as parametric experiments. 12,13 To overcome the shortcomings of standalone tools, we studied and implemented a general web-based modeling and simulation environment for multi-domain electromechanical systems. Web-based simulation (WBS) is the integration of web and simulation technology.…”
