The simulation aims to develop a numerical model that replicates the experimental process within an acceptable computational time. Compared to the real experiment, the model is scaled down or up in both temporal and spatial scales, making direct quantitative comparison with the experiment infeasible. However, trend variations in the model can provide valuable insights for a deeper qualitative understanding of the experimental results. The model geometry of the extrusion process in the SF battery electrode manufacturing, used by our lab collaborators , is illustrated in Fig. .
