Abstract
The Uncertainty Quantification Module, an add-on to the COMSOL Multiphysics® software, is designed
to address the limitations of deterministic simulations by incorporating the inherent uncertainties found
in real-world applications. Simulations typically assume that input data are fixed, and outputs can be
computed with high accuracy. However, this deterministic approach does not account for the variability
present in practical scenarios such as manufacturing processes, where significant uncertainty exists.
The Uncertainty Quantification Module offers a uniform interface for screening, sensitivity analysis,
uncertainty propagation, reliability analysis, and inverse UQ. It can be integrated with other COMSOL
products to enable uncertainty analysis in electromagnetics, structural mechanics, acoustics, fluid
dynamics, heat transfer, and chemical engineering simulations. The software brings fully coupled
Multiphysics and single-physics modeling capabilities, model management, and user-friendly tools for
building simulation applications.

In this presentation, we will first introduce the COMSOL Multiphysics software and demonstrate the
workflow by constructing a simple proof of concept model. We will then discuss the Uncertainty
Quantification Module, and how it can be incorporated into a Multiphysics simulation.
