Dynamic Simulation of Energy Systems.

LTX Simulation GmbH specializes in the energy analysis of technical systems. Located in Munich, we leverage modern simulation technology for industrial engineering applications.

In research and development projects, we concentrate on thermodynamic processes, e.g. in HVAC applications or power plants.

LTX develops complex mathematical models and corresponding customized software.

Time-dependent interaction with controllers is crucial for modern products and industrial plants. For analyzing these complex systems, we build integrated simulations of mechanical, electrical, thermal, hydraulic, pneumatic and chemical processes together with dynamic control behavior.

We provide modeling and simulation services for specific system components as well as complete systems. Additionally, we develop customized software solutions, e.g. for pre- and post-processing tasks.

Customers benefit from existing modeling know-how and Modelica simulation tools.

Our models are mostly based on the open-source modeling language Modelica and the Modelica-based simulation tool Dymola.

In order to leverage existing modeling know-how, we distribute Modelica Libraries developed by specialized developers and research institutes.

We provide technical support and consulting for the simulation tool Dymola. Additionally, we offer specialized consulting and comprehensive training classes.
