SimulationX is a CAE software application running on Microsoft Windows for the physical simulation of technical systems developed and sold by ESI ITI GmbH in Dresden, Germany.

In the mid 1980s, VEB Mikromat in Dresden developed a program for DOS to design controlled feed axis systems and to perform hydraulic calculations. In 1993, ITI GmbH, founded by former Mikromat employees in 1990, introduced a simulation tool for Microsoft Windows designed for calculations of drive systems: ITI-SIM 1. With the release of ITI-SIM 2 in 1995, the software also allowed for fluid simulations. In 2002, the newly developed application SimulationX, based on the object-oriented description language Modelica, was introduced to the market. By the year 2007, ITI-SIM (then in version 3.8) had been completely replaced by SimulationX.

Since the beginning of 2016, ITI belongs to the ESI Group and now operates under the name ESI ITI GmbH.

Simulation models are created on the basis of a discrete network approach. That means the system is broken down into logical parts which are linked through specific connections. These sub-systems are represented by preconfigured or custom model elements organized in domain-specific and custom model libraries. The sub-models are then parameterized and connected with each other. Models can be created either through the graphical user interface or by using Modelica command lines.

Model libraries can be obtained as modular packages from the software producer. There are various libraries available with basic models for the corresponding physical domains as well as libraries with advanced models for specific applications and industries. Depending on the objective, the user can choose from 1D, 2D and 3D model elements with respect to the modeling, simulation and parameterization requirements. Modelica-based third-party and custom-built libraries can also be integrated into SimulationX.
