Navigate to: Analyze > Set Analysis Options . Select "Nonlinear (P-Delta)" and "Buckling (Eigenvalue)." The "Ultimate" solver will run both simultaneously. On a standard i5 processor, a 20-story model with 15,000 shells and frames solves in under 90 seconds. (CSI), is a general-purpose finite element analysis (FEA)
CSI SAP2000 V15.2.1 Ultimate is a legacy version of the industry-standard structural analysis and design software. While newer versions (like v25+) offer significantly more advanced BIM integration and updated building codes, V15.2.1 remains a "workhorse" for engineers using older hardware or maintaining legacy projects.
