7 Technical Principles Reduced Order Modeling Robust Design
8 Reduced Order Models Level of Description Accurate but too large for (most) available analysis and design tools Model Reduction System Identification Reduced-Order Models Compact Models CFD /HT Simulations The Desired Compromise: Sufficiently accurate and within scope of most analysis and design tools Fits into available tools but lack Lumped Parameter Models predictive capabilities Model Size (DOF) < , ,000
9 Y Robust Design Response Deviation at Optimal Solution Deviation at Robust Solution Objective Function Optimal Solution 2 x Robust Solution Design Variable Optimization minimizes the function of expected response Robust solution also minimizes variation in the response * X *N.
