Welcome at the website of the CP4GE research group

The Computational Physics 4 Green Energy (CP4GE) group of Prof. Dr. Lohbreier offers multiphysical simulations to support partners in industry and academia during the development or improvement process of green technologies. To acquire a better understanding, computer simulations provide many advantages and unique possibilities compared to experimental methods.

The world around us is determined by the laws of physics which are typically described by partial differential equations (PDEs). However, current problems in academia and industry are often too complex to be solved analytically. Numerical simulations are the method of choice: the questions are formulated as a numerical model and the PDEs can be

solved approximately. A well-established numerical technique to solve these equations is the Finite Element Method (FEM). Additionally, in many applications, considering only one physical aspect is not enough. More equations - corresponding to two or more physical regimes - need to be solved in a coupled manner. This is what makes up "multiphysical simulation" and defines our area of expertise. Besides the simulative expertise, each group member is an experienced experimental physicist. The team is always interested in conducting accompanying experiments in the laboratories at the Nuremberg Institute of Technology or at the R&D laboratories of the project partner. This combination of simulative and experimental expertise is beneficial for the validation of the simulation model.


Our interest focuses on the development, improvement and optimization of green technolgies, with the help of multiphysical numerical computer simulations. Current research fields are

  • Hydrogen Fuel Cell (PEMFC)
  • Electric Transport Systems
  • Energy Harvesting
  • Coating Processes

Since many years, computer simulations have been established as a “third pillar” in R&D. If you are involved in a R&D process and problems encountered which you cannot solve satisfactorily with your methods, multiphysical simulations might be benefical for you. Because numerical simulations allow a deep insight, our methods can contribute to a better understanding of your process.The group is constantly interested in new projects.
