We exploit the multisymplectic character of the integrator to analyze the energy and momentum map conservations associated to the temporal and spatial discrete evolutions.multisymplecticLie grouptime and space integratorbeamNoether theoremMultisymplectic Lie group variational integrator for a geometrically exact beam in R3text::journal::journal article::research article
