The Design Your Tokamak (DYT) program suite is a collection of modules aiming to explore different configurations and establish reliable boundaries for possible machine designs. In the presented work DYT was used to examine the minimal in-plane coil-to-coil force acting on poloidal field coils during operation in small ELM regimes. The operation within the small ELM regime is determined using the shaping parameters and the normalized pressure gradient in the pedestal region. By comparing various plasma elongations for ASDEX-Upgrade, JET, ITER, and DEMO scenarios, the study identifies a favorable plasma shape that reduces the maximum force exerted on the coils. Building on this approach and recognizing the importance of impurity seeding for power exhaust in large machines like ITER or DEMO, a module to investigate the radiated power within the separatrix for different impurities will be implemented into the simulation tool. The objective is to generate insights and a tool that may enhance the safe and effective construction of future fusion reactors.
