Understanding Finite Element Analysis

FEA is a numerical technique used to find approximate solutions to complex engineering problems. It involves dividing a structure into smaller, simpler parts called finite elements. Each element is analyzed individually, and the results are combined to understand the behavior of the entire structure. This method is particularly useful for analyzing stress, strain, heat transfer, and other physical phenomena.
