Beamforming MBSE workflow using New Ansys SysML V2 Modeler and the MBSE Methodology

This presentation discusses the implementation of Ansys MBSE Methodology through the creation of a Digital Beamforming Workflow using Ansys SysML v2 Modeler. Starting from a definition of the fundamental concepts of Authoritative Source of Truth, Views, and Digital Threads, it is shown how these concepts can be used as the basis for defining the MBSE methodology to be implemented within the new Ansys SysML v2 Modeler. The use case considered involves developing a Digital Beamforming (DBF) system for a UAV that communicates with a ground station, ship, and satellite using a phased array antenna. The objective is to ensure an adequate link margin between the UAV and ground station using a DBF transmitter and receiver system. This use case is considered at the System of Systems level, enabling us to derive the requirements up to the DBF’s subsystem level, define the form and function of the system and perform a trade study to finalize the high-level architecture. The work involves the development of the DBF System Architecture Model (SAM) in the Ansys SysML V2 Modeler based on a predefined Project’s Design Reference Mission (DRM) in Ansys STK, and thereafter connecting the system model to analytical workflow modeled in Ansys ModelCenter. Trade Studies are subsequently performed at different fidelity levels, where low fidelity analysis is performed using canonical equations and higher fidelity analysis is performed using Ansys STK for link margin analysis. This work shall form the base for future works where connection and simulation capabilities of Ansys SysML v2 Modeler with Ansys STK, Ansys ModelCenter, and other system tools like Ansys Medini & Ansys SCADE can be further explored.
