The Centroid Method for the Calibration of a Sectorized Digital Twin of an Arch Dam

In this article, a digital twin is numerical model of dam–foundation system with physical basis. A exhibits complex behavior and, therefore, significant simplifications are necessary for to be feasible, which reduces model’s accuracy. Differences in the material characteristics particular regions dam and foundation usually not considered. An important reason that high computational cost calibrating when many parameters must optimized such way calibration becomes unfeasible. new, simple, accurate, low time-consuming algorithm, centroid method, presented allows system. The extreme efficiency algorithm opens feasibility sectorized an arch dam, so obtained takes into account different or sectors foundation, more closely approaching
