From Start to Finish - A Process of Using Simulation Software in Energy Research Projects

Simulation software is crucial in energy research, serving as a key tool for analyzing complex systems and testing innovative solutions. Simulations are used in this context because real-world testing is typically expensive and time-consuming and may jeopardize the stability and safety of critical infrastructure systems. As part of NFDI4Energy, we are developing services to support researchers in effectively integrating simulation into their workflows. To better understand the research community's needs, we developed and analyzed multiple use cases that illustrate the diverse simulation-based processes in energy research. Based on these, we designed a structured process model that guides the use of simulation software, from planning and the initial setup over the execution to sharing results following the FAIR principles. Notably, the process also emphasizes the value of sharing simulation models and software, not just data, via dedicated software registries, thus enabling research data management. Our goal within NFDI4Energy is to create new tools and services while integrating and connecting existing solutions through a shared service portfolio. This paper presents an overview of the identified requirements and the conceptual design of a Simulation-as-a-Service (SimaaS) approach tailored to the energy research domain, offering early insights into a potential future service landscape.
