[en] This paper investigates the application of the POD method to dynamic systems evolving on a Lie group. More precisely, the construction of the snapshot matrix and the definition of the projection operation on the Lie group are addressed. A numerical study based on an highly elastic beam with large 3D motion is developed to illustrate the theoretical concepts. The influence of the choice of the initial Lie group structure, of the definition of the snapshot matrix and of the projection scheme are investigated numerically.
