Reduced order modeling is an approach that combines concepts from data science, modeling, and simulation as a means of lowering the computational cost of models while maintaining high levels of realism in significant system components. It is considered an effective approach that enables real-time analysis and lessens the computing strain brought on by high-dimensional uncertainty quantification (UQ) problems. Because of market demands for shorter design cycles that produce higher-quality products, ROM processes have grown in popularity in the product development industry. DEP’s highly automated Reduced Order Modeling techniques promote simplified model updating processes, which in turn drastically reduce the run-time, accelerated by fast design iterations.
