Reverse engineering of initial and boundary conditions with TELEMAC and algorithmic differentiation

Abstract

The TELEMAC-SUITE with Algorithmic Differentiation (TELEMAC-AD) calculates the impact of a high number of spatially distributed parameters on flow conditions. This technique is a revolutionary step forward in open channel flow simulations, as it solves previously unsolvable or computationally very expensive problems. Classic simulation methods return the combined impact of many parameters, whereas the adjoint version of TELEMAC-2D returns the individual influence of every single parameter in one run. A wide range of new applications is now possible with the TELEMAC-SUITE: Automatic optimization and calibration of flow relevant shapes, data assimilation, high resolution sensitivity analysis or inverse modeling
