Talk:SimulationX

Hello,

I would like to propose several neutral, verifiable updates to the SimulationX article to reflect developments since the last major revision. I am professionally associated with the software and therefore am disclosing a conflict of interest and requesting that any uninvolved editor review and implement these changes if appropriate.

Summary of proposed updates:

Corporate ownership update (2025): ESI Group has been acquired and integrated into Keysight Technologies. SimulationX continues to be developed as part of the Design Engineering Software and Computer-Aided Engineering portfolio.

Recent software development (2024–2025): Addition of current information on recent major releases, including updates to battery, thermal-fluid, and energy system libraries, improvements to FEM import (beta), enhanced FMU export workflows, and user-interface improvements.

Modern workflows and standards: Expanded mention of Functional Mock-up Interface (FMI/FMU), hardware-in-the-loop (HiL), real-time simulation, and model-based systems engineering (MBSE) integration.

Expanded industry use cases: Inclusion of growing use in electrification, energy storage, hydrogen systems, and smart energy infrastructure.

Licensing model: Addition of a short neutral section describing the modular, token-based licensing scheme introduced in recent versions.

All proposed changes are based on publicly available, verifiable sources (product documentation, press releases, technical publications). I will be happy to provide independent references for each item if needed.

Also the InfoBox needs to be updated:

Thank you for your time and consideration. MajidNas (talk) 11:58, 5 December 2025 (UTC)

SimulationX is a proprietary computer-aided engineering (CAE) software application for the physical simulation of technical systems. The software runs on Microsoft Windows and is developed by ESI ITI GmbH, formerly ITI GmbH, which is now part of Keysight Technologies following the acquisition of ESI Group in 2025.

In the mid-1980s, VEB Mikromat in Dresden (then East Germany) developed a program for MS-DOS for the design of controlled feed-axis systems and hydraulic calculations. In 1990, former Mikromat employees founded ITI GmbH. In 1993, ITI released ITI-SIM 1 for Microsoft Windows, designed for dynamic simulation of drive systems. With ITI-SIM 2 in 1995, the software was extended to include fluid simulations.

In 2002, the Modelica-based successor SimulationX was introduced as a new object-oriented simulation environment. By 2007, ITI-SIM (version 3.8) was completely replaced by SimulationX.

In 2016, ITI GmbH became part of ESI Group and was renamed ESI ITI GmbH. In 2025, ESI Group was acquired and integrated into Keysight Technologies. Since then, SimulationX continues to be developed as part of Keysight’s system design and simulation software portfolio.

SimulationX is based on a discrete network modeling approach. Technical systems are decomposed into logical sub-systems that are represented by interconnected model elements. These sub-models can be parameterized and combined to simulate the dynamic behavior of the overall system.

Models can be created using a graphical user interface or by means of Modelica-based textual modeling, enabling the development of large multidisciplinary system models.

SimulationX provides modular, domain-specific model libraries for system simulation. These include mechanics and multibody systems, power transmission, electrical engineering, fluid power (hydraulics and pneumatics), thermal-fluid systems, torsional vibration analysis, and subsea systems. In addition, Modelica-based third-party and user-defined libraries can be integrated into the software environment.

SimulationX supports the Modelica modeling language for the development and execution of custom models. Models from the Modelica Standard Library and other Modelica-compliant libraries can be directly executed within the software.

SimulationX provides interfaces for data exchange and co-simulation with other engineering tools. These include CAD systems, finite-element analysis (FEA/FEM), computational fluid dynamics (CFD), and computer-aided optimization software. The software supports co-simulation via the Functional Mock-up Interface (FMI) standard and the exchange of Functional Mock-up Units (FMUs).

SimulationX is used in hardware-in-the-loop (HiL), rapid control prototyping, and real-time simulation environments, and can be coupled with external test and simulation platforms. More recent versions support workflows related to model-based systems engineering (MBSE) and system-level digital validation.

SimulationX is used for the design, modeling, and analysis of complex mechatronic systems as well as for virtual testing in various industries, including automotive, railway, shipbuilding, heavy machinery, power generation, building technology, aerospace and defense, mechanical engineering, medical engineering, oil and gas, and consumer electronics.

In recent years, the software has also been applied increasingly in the fields of electrification, energy storage systems, electric vehicle powertrains, hydrogen systems, and smart energy infrastructure.

SimulationX is used in education and research worldwide. It is applied in academic research on topics such as electric mobility, renewable energy systems, multibody dynamics, fluid power, and control system development.

SimulationX follows a modular, token-based licensing concept that allows users to select specific functional modules and domain libraries according to their requirements. This enables flexible use across different technical disciplines and project sizes.

SimulationX is a multiphysics, Modelica-based system simulation platform that integrates mechanical, electrical, thermal, and fluid-power domains within a single environment. Its integration into Keysight Technologies in 2025 positions it within a broader ecosystem of electronic design, measurement, testing, and system validation tools.
