(a) Briefly explain the steps in finite element analysis.
Explanation
Finite element analysis is a numerical method used to solve partial differential equations. The steps involved in finite element analysis include mesh generation, where the domain is discretized into elements; element formulation, where the behavior of each element is defined; assembly of the global stiffness matrix, where the element matrices are combined to form the global matrix; solution of the global equations, where the unknowns are solved for; and post-processing, where the results are analyzed and visualized.
