Our team surrounding Dr.-Ing. Manuel Gräber and Dr.-Ing. Franz Lanzerath brings experience and best practices from many simulation projects. Thanks to our proximity to research, we are familiar with the latest methods and topics and incorporate them into our work.
This enables us to accompany our customers on the fastest path to virtual prototypes, reliably find errors and develop the best solutions.
We are not only home in the virtual world. We are also on the test bench and know the problems and challenges of the real world.
On request, we can set up individual test benches for you with our partner company TLK-Thermo and carry out measurements. The perfect complement for your virtual prototypes.
For more than 15 years, our thermodynamics and simulation expertise has been incorporated into our Modelica library TIL, which has proven itself in countless industrial projects.
Our model code is openly comprehensible and can be individually extended and tailored to your needs.
Many interfaces for integrating the simulation models into your existing software environment (e.g. Matlab Simulink).
You describe your use case. We then discuss possible solutions, software tools and methodologies. Finally, we calculate the budget and schedule.
The project team gets to know each other and we clarify questions about cooperation (e.g. data exchange). You get to know your contact person and we plan the next steps in concrete terms.
We work independently on our jointly defined roadmap. In regular meetings, we present interim results, coordinate and adjust goals. We always keep an eye on the budget.
You receive extensive rights of use and can also use the code we generate in the context of other partnerships and projects.
Yes, but of course confidentiality is important to us. Your information is safe with us. We will gladly conclude a confidentiality agreement with you.
All rights to inventions that arise in the project belong to you. We will be happy to support you with the patent application if necessary.

To support technical sales at NEUMAN & ESSER, we have developed a customized web-based application for the dynamic simulation of hydrogen refueling stations.
Customer requirements such as type and number of refueled vehicles can be selected. The filling station can be configured in detail and in a simulation the dynamic behavior of the overall system is calculated for a typical period of time.
With this tool, sales staff can configure the product "filling station" according to customer requirements without time-consuming detours via engineers. Interested parties receive direct and detailed feedback.

Emerson develops components and systems for supermarket refrigeration. Due to its environmental benefits CO2 as refrigerant is becoming more and more important in this sector. But compared to traditional refrigerants the thermodynamic properties of CO2 are totally different (high pressures and low critical temperature). Designing efficient CO2 cycles is challenging and there are many different cycle concepts proposed. Together with Emerson experts we have developed simulation models for a number of different concepts and run a simulation study to compare the seasonal efficiency of these cycles.

In their development process of heat pump controllers Vaillant has established a comprehensive testing strategy. Before they connect developed controllers to real heat pumps in their lab, they are connected to virtual heat pumps running on special real time simulation hardware and software from dSPACE. Crucial ingredients for this so-called Hardware-in-the-Loop (HiL) tests are simulation models of the heat pumps, that are accurate, fast and robust. We developed these models for Vaillant using our Modelica library TIL Suite and set up a reliable tool chain to export these models to dSPACE platform. The models include a full dynamic physical model of the refrigeration cycle. It can handle switching of refrigerant flow direction caused by different modes for defrost, heating and cooling. Vaillant is now able to detect issues in control code much earlier and saves with this virtual testing a considerable amount of expensive lab experiments.

Together with Volkswagen we have developed simulation models for battery thermal management systems. Geometry of cooling plates and its flow patterns are taken into account by discretization with finite volumes. Compared to detailed CFD simulations the spatial resolution is much lower but still high enough to achieve confident results. This approach reduces the computation time dramatically enabling usage of numerical optimization algorithms or large-scale simulation studies. Cooling systems can be designed with less pressure loss and increased energy efficiency.
