Enhancements: To facilitate lateral stability design, an automated feature for minimum pile tip embedment has been added to the "Lateral Stability" page. This feature streamlines the process of generating and analyzing models over a given range of candidate embedment lengths. Models are automatically analyzed in bulk, and post-processed results can be viewed from the Design Tables.
