User Manual for the SU2 EQUiPS Module: Enabling Quantification of Uncertainty in Physics Simulations

Abstract

This document serves as the manual for using the EQUiPS (Enabling Quantification of Uncertainty in Physics Simulations) module in SU2. The EQUiPS module uses the Eigenspace Perturbation methodology to provide interval bounds on Quantities of Interest (QoIs) that capture epistemic uncertainties arising from assumptions made in RANS turbulence models. This has been implemented and tested in SU2 for a variety of benchmark turbulence cases as well as flows of aerodynamic interest.
