A Finite Element Method (FEM) developer creates software to simulate physical phenomena by dividing it into smaller, simpler parts, called finite elements. They write code to solve complex mathematical equations representing these elements, often using FEM libraries. Their work aids in predicting how structures or materials will behave under various conditions, aiding in fields like engineering, physics, or materials science. They also verify and validate models, refining them for accuracy. Additionally, they may collaborate with scientists or engineers, translating their specifications into software solutions, and continually update and maintain their software to ensure optimal performance.
