The Department of the Army, Army Contracting Command – Aberdeen Proving Ground (ACC-APG), Natick Division, intends to award a sole source purchase order to ANSYS, Inc. for the renewal of the ANSYS LS-DYNA Site License and associated software maintenance and technical support. The LS-DYNA software is a finite element analysis (FEA) platform used to perform physics-based simulations supporting the Aerial Delivery Directorate (ADD). The software enables engineers to conduct advanced modeling and simulation activities, including Finite Element Analysis (FEA), Fluid-Structure Interaction (FSI), and Computational Fluid Dynamics (CFD). • The software is used to evaluate system performance for aerial delivery applications, including parachute systems, aircraft components, vehicle airbag systems, and other extraction and deployment systems. • The software allows engineers to analyze how systems respond to applied loads, acceleration forces, and dynamic environments and helps identify potential structural or system failure modes prior to physical testing. • The anticipated period of performance is 01 April 2025 through 31 March 2026.
