Modelling and simulation

FjXxp__C6Pn6tvuu47W7jqz-iJfvBQnLI8vuBxq3FTI.jpg
In the research field of modelling and simulation, many application examples from the other TREE research groups are worked on cross-sectionally. At the same time, there is a strong focus on independent method development in order to be able to process and solve the latest technical problems with computer support at all times. This naturally results in close co-operation between natural and engineering scientists and between experimentalists and simulators from the various fields of research

„No modelling and simulation - no technical innovation. In this field of research, we deal with the backbone of system development and look in all directions: technical innovations, sustainability, scalability and cost optimisation.”

Working groups

bild_1.jpg

Computational Chemistry working group

Scientific computer simulations are able to significantly expand our understanding of the relationship between theories and experimental observations. Especially when macroscopic observations need to be explained, simulations at the micro level provide an insight into the actual causal relationships that often remain hidden from the experiment.

Structural analysis and optimisation working group

The working group deals with the simulation and mathematical optimisation of structural components based on the finite element method (FEM). In addition to modelling, the focus here is also on experimental and numerical methods for identifying the required material parameters. For thermoplastic materials in particular, such as those used in the extrusion blow moulding of hollow plastic bodies, it is necessary to consider and model the (manufacturing) process-related changes in material properties.

 

About the working group
Lattice-Boltzmann-Methode_Kanalströmung

Lattice-Boltzmann Methods Working Group

In recent years, the Lattice-Boltzmann method has proven to be a sophisticated tool for flow simulations. Compared to existing Navier-Stokes solvers, the Lattice-Boltzmann method enables efficient methods for calculating turbulent, thermal or multiphase flows.

Networks working group

The working group deals with the modelling and simulation of infrastructure networks. In particular, it focuses on water, gas, electricity and heating networks on different scales, which can range from a household to supra-regional interconnected networks. With the help of computer experiments based on mathematical simulation, current issues relating to energy efficiency and security of supply and thus contributions to the energy transition can be provided.

AErOmAt - Aerodynamic energy optimisation through metamodel-supported adaptation of structures

The efficient utilisation of available energy is one of the great challenges of our time. The analysis and optimisation of shapes and structures with regard to their aerodynamic properties is of particular importance. Important areas of application are the development of energy-efficient vehicles and wind energy technology.

MOTTSAL - Modelling and Optimisation of Transdermal Therapeutic Systems

By taking into account the patient characteristics of skin type, skin texture, transpiration behaviour etc. in the design of the transdermal therapy systems TTS (active ingredient therapy patches), the effectiveness of the active ingredients could be increased and the side effects reduced through a combination of optimised dosage and skin-adapted behaviour.

ReBauVES - Resource-optimised component development

In the development process of extrusion blow-moulded components, the use of FEM structural analysis is now state of the art. Product properties such as stackability can be predicted with good accuracy. However, it is very time-consuming to determine the material parameters required for a meaningful simulation. Due to the stretching of the material in the blow moulding process in conjunction with high cooling rates, the properties of thermoplastic materials are significantly influenced by the manufacturing process.

EWave

The aim of EWave is the development of an innovative energy management system, the calculation of energy-optimised operating plans for the water extraction, treatment and distribution plants operated in the supply system, the coordination with the fluctuating energy supply from own generation plants and the energy procurement from one or more energy supply companies as well as the pilot application at the Rheinisch-Westfälische Wasserwerksgesellschaft mbH (RWW).

SkaSim - Scalable HPC software for simulations in the chemical industry

The use of force field-based molecular dynamics (MD) simulations makes numerous practical problems in engineering accessible to modelling and simulation for the first time. Technically relevant systems can be analysed safely and reliably on the basis of physically meaningful molecular interactions. The industrial development of new products and resource-efficient processes will be fundamentally changed by the use of highly scalable molecular simulations.
