The digital reconstruction and resurrection of the RMS Titanic ’s sinking

This work presents a supercomputer-based digital reconstruction of the RMS Titanic’s sinking using advanced nonlinear finite element analysis (NLFEA) and computational fluid dynamics (CFD) simulations. The modeling reproduces the sequence of events from iceberg collision and progressive flooding to structural failure and ultimate hull-girder breakup. A counterfactual head-on collision scenario is also investigated to assess whether the vessel might have remained afloat under such conditions. To enable these large-scale simulations, continuous welded structural models were developed to represent the ship’s original riveted hull, informed by archival blueprints, wreck-site evidence, and historical testimonies for validation. All computations were carried out on the high-performance computing facilities at University College London. The findings, featured in Titanic: The Digital Resurrection (BBC and National Geographic, April 2025), commemorate the 113th anniversary of the disaster and provide the most comprehensive and technically accurate visualization of the sinking to date.
