Uncertainty Quantification Module
COMSOL Multiphysics® version 6.0 introduces the new Uncertainty Quantification Module. This product is an add-on to COMSOL Multiphysics® and is used for understanding the impact of model uncertainty — how the quantities of interest depend on variations in the inputs of a model. It provides a general interface for screening, sensitivity analysis, uncertainty propagation, and reliability analysis. The Uncertainty Quantification Module can efficiently test the validity of model assumptions, convincingly simplify models, understand the key input to the quantities of interest, explore the probability distribution of the quantities of interest, and discover the reliability of the quantities of interest.
The assurance of model correctness and increased understanding of the quantities of interest aid in reducing costs in production, development, and manufacturing. Any uncertain model input, whether it be physics settings, geometric dimensions, material properties, or discretization settings, can be treated as an input parameter, and any model output can be used to define the quantities of interest.
The Uncertainty Quantification Module can be used with products throughout the COMSOL product suite for analyzing uncertainties in electromagnetics, structural, acoustics, fluid flow, heat, and chemical engineering simulations. You can combine it with the CAD Import Module, Design Module, or any of the LiveLink™ products for CAD.
