Beyond Ritz-Galerkin: Finite element approximations on a manifold in the configuration space [Abstract]

Wackerfuß, Jens
Schröppel, Christian

An extension of the Ritz-Galerkin method, based on finding approximations on a finite-dimensional manifold of functions (i.e., not a linear subspace) in the infinite-dimensional exact configuration space, will be presented. This new approach is particularly efficient in computing geometrically exact solutions for problems involving large rotations.
