Reduced-order models for aeronautics based on the LATIN-PGD method within non-linear industrial Simcenter Samcef software

Résumé

A weakly-invasive version of the LATIN-PGD method is described to build reduced-order models within general-purpose industrial finite element software, such as Simcenter Samcef™ developed by Siemens Digital Industries Software. The originality of the approach lies in its generic character, which allows to manage of all types of non-linearities classically encountered in solid mechanics: material, geometric and contact non-linearities. Results are illustrated through two industrial test-cases and show impressive performance gains. Such reduced models or virtual charts can then be broadly used to deploy Digital Twins.
