Minisymposium description:
------------------------- 

This mini-symposium is concerned with recent developments  in geometric time integrators 
for the class of mechanical systems  described by a stationary action principle. Such 
variational integrators are known to obey the underlying physics in the sense  that 
they introduce no artificial numerical dissipation and preserve  the geometric structure 
including the symplectic or multi-symplectic  structure, conservation of angular momentum, 
and/or conservation of  circulation when applicable. In this mini-symposium, the presentation 
will be centered on new results in discrete variational solid and  fluid mechanics, including 
those based on discrete Hamilton- Pontryagin principles.
