An Open-Source Graphical Composite Modeling Editor and Simulation Tool Based on FMI and TLM Co-Simulation

Abstract

A common situation in industry is that a system model (here a composite model) is composed of several submodels which may have been developed using different tools. FMI is one important technology for exporting/importing models between tools and/or connecting them via co-simulation. TLM based modeling and co-simulation is another important technique for modeling, connecting, and simulation of especially mechanical systems, which is simple, numerically stable, and efficient. A number of toolspecific simulation models, such as Modelica models, SimuLink models, Adams models, BEAST models, etc., have successfully been connected and simulated using TLM based co-simulation. However, previously there was no general open source tool for creation, graphic editing, and simulation of composite models connected via FMI or TLM based co-simulation. In this paper we present a graphical composite model editor based on OpenModelica which is integrated with the OpenModelica and the SKF TLM co-simulation frameworks to support both FMI and TLM based composite model editing and simulation. The editor supports creating, viewing and editing a composite model both in textual and graphical representation. The system supports simulation of composite models consisting of sub-models created using different tools.

An Object-Oriented Modeling Approach to Virtual Prototyping of Marine Operation Systems Based on Functional Mock-Up Interface Co-Simulation

“…Co-simulation provides a feasible solution for computation speedups at modest loss of accuracy. The overall simulation performance is also dependent on the co-simulation master [24]. Advanced Co-simulation Open System Architecture is an ongoing project that will address the questions this dissertation leaves unanswered [25].…”

On Standardized Model Integration : Automated Validation in Aircraft System Simulation

“…The two sub-system models presented in Figure 3.1 are developed in Dymola and the corresponding simulation application is implemented as a Composite model in OMSimulator using the graphical editor OMEdit [55], see Figure 3.2a. A Composite model is a simulator in OMSimulator consisting of models exported from any FMI supporting modeling tool or a tool supported by tool-to-tool coupling [VIII].…”

Methods and Tools for Efficient Model-Based Development of Cyber-Physical Systems with Emphasis on Model and Tool Integration

“…The work on model-based dynamic optimization presented in [103] and [104] are covered in Chapter 3. The TLM-based approach for comodeling and simulation framework developed in [76] is presented in Chapter 4. The approach to collaborative modeling and traceability support introduced in [77] is elaborated in Chapter 5.…”
