Finite Element Analysis (FEA) is a numerical method that divides structures into smaller elements to solve complex engineering problems. Popular FEA software for structural engineering includes ANSYS, Abaqus, NASTRAN, and SOLIDWORKS Simulation. These tools offer various features and capabilities to analyze complex structures, including linear and nonlinear analysis, contact analysis, and optimization. FEA is a powerful tool for structural engineers, allowing them to predict the behavior of structures under various loads and conditions, reducing the need for physical testing and improving the overall design process.

The use of finite element software is crucial for structural analysis due to the number of elements and the time-consuming nature of the process. The structural modeling process is independent of architectural drawings. This means that structural engineers must generate the geometry of structural modeling in a different environment, such as SAP2000. However, Autodesk has solved this issue by introducing BIM and BIM360 to integrate structural and architectural drawings to eliminate interface problems. Autodesk has also created a software called Robot for structural analysis and design, which incorporates Revit to transfer information seamlessly. The CSI company provided the API code to integrate their software with other software.
