Reduced-Order Model (ROM) Applications in A&D

A systems simulation is a collection of models, simulations and algorithms that predict how all the parts in a system will work together. As you build the system model, you will need to account for different physics. The fidelity of the model will improve as these physics are coupled into one simulation. The challenge with creating a systems simulation is that the 3D models that predict the performance of each part take a considerable amount of time and computational resources to solve. One solution is to use reduced-order models (ROMs) that can help system-level simulations run close to real time.

ROMs are simplifications of 3D models that preserve the essential information that is used for system simulations. Solving a ROM for a given input can be orders of magnitude faster than solving a 3D model. This makes ROMs ideal for many applications, like design of experiments (DOE), systems simulations, digital twins and runtime generation of real-time applications. Ansys Twin Builder can connect third-party tools and 3D models within a system’s simulation through ROMs.

This webinar will present an overview of ROM technology available with the Ansys platform, along with some examples relating to the Aerospace & Defense industry and a demo of the ROM workflow for CFD.
