**Molecular Simulation**

Numerical simulations at an atomistic level have many
applications in scientific and technologic areas – such as
biology, nanosciences, crystaline solids, … Whereas most of
the people active in this field are concerned with relevant
applications (to actual problems), it seems also useful that some
of them turn to the improvement of the methods themselves and
their implementations, in collaboration with (applied)
mathematicians. The aim of this ACI is to improve all numerical
methods for molecular simulation, ranging from quantum chemistry
to molecular dynamics, in link with coarser scales, and try to be
relevant for as many applicative communities as we can: biology,
condensed matter physics and mechanics, fluid physics, chemistry.
