Driven by a high digitalization context with Digital Twins, reduced-order modeling (ROM) methods are becoming increasingly coveted by the industrial sector, keen to benefit from new tools and robust techniques that allow faster computations.However, the spread of these ROM methods within commercial finite element software is currently hindered by two main obstacles: non-intrusiveness and robustness. This arises directly from the nature of the associated algorithms involving many unconventional operations and thus preventing from getting robust and reliable tools all integrated into one certified product. This thesis introduces a weakly-invasive reformulation of the LATIN-PGD method designed to compute and improve reduced-order models direct...
