Added a nonlinear multi-step static load case type, allowing for more complex simulation of independent steps in a single case. Technical and Installation Details

Supports sophisticated techniques like Fast Nonlinear Analysis (FNA), large deformation analysis, and P-Delta effects.

Enhanced DirectX graphics provide faster model navigation, fly-throughs, and rotations.

Includes specialized tools for modeling incremental or segmental construction, accounting for time-dependent material behaviors like creep and shrinkage.

Fully integrates design for steel, concrete, aluminum, and cold-formed steel frames based on various international standards. Enhancements in Version 21

Version 21 introduced several significant technical upgrades over its predecessors:

Features a dedicated module for offshore structures, including automated wave load generation and API 4F wind loading.
