This build features an optimized nonlinear solver. In previous versions, running a staged construction analysis on a 60-story building with nonlinear hinges could take days. Version 20.2.4 optimized the algorithm for static nonlinear (Pushover) and time-history analyses, allowing for faster convergence in the Newton-Raphson iteration method.
Suitable for older hardware or legacy workstations. However, it is limited in the amount of RAM it can utilize, which may slow down the analysis of very large models. CSI ETABS 2018 Version 20.2.4.1228 -32-64 Bit- Download
