The Thematic Research Unit Couplings and Numerical Methods for Complex Structures (TRU MECNUM) brings together researchers who develop research activities around advanced numerical approaches, their efficient implementation and the associated theoretical foundations.

These developments are aimed at finding answers to problems that cannot be satisfactorily addressed with industrial numerical tools (strong non-linearities, coupled physics, large-scale problems, etc.).  The members of this TRU also stand out for the development of ad-hoc computing codes, from proof-of-concept to distributed parallel libraries that can be run on supercomputers. Although relatively upstream, the developments carried out within the framework of this TRU remain motivated by practical issues, enabling us to respond effectively to scientific or industrial needs, or to optimize currently available computing resources.

The scientific themes developed within the TRU are broken down into four research areas.
