What is Mesh Optimization in ETABS & SAP2000 about?

This document summarizes the results of a finite element analysis of a cantilever beam modelled with different mesh sizes using ETABS and SAP2000 shell elements. Finer meshes with an aspect ratio of 1 provided results that most closely matched hand calculations. Coarser meshes underestimated deflections. For building models in ETABS, the mesh aspect ratio is more important to control than element size. Wall elements should be meshed with lines following the wall length for long walls or storey height for sh
