Finite Element Modeling

Definition

Finite Element Modeling (FEM) is a computational technique used to predict how structures behave under various physical conditions by breaking down complex shapes into smaller, simpler parts called elements. This method allows for the analysis of mechanical properties, thermal dynamics, and electrical behavior in materials, which is essential for understanding the interactions within solid-state battery systems and can play a significant role in dendrite suppression.
