We perform multi-ion molecular dynamics (MIMD) simulation and apply to
calculate the ionic structures and x-ray elastic scattering of different charge-state
ions in the warm dense matter regime. Firstly, the method is self-consistently
used to calculate electron structures of different charge-state ions in the ionic
sphere, in which the ion-sphere radii are determined by the plasma density and
their charges. And then the ionic fraction is obtained by solving the Saha
equation, taking account of interactions among different charge-state ions in the
system, and ion-ion pair potentials are computed by the modified Gordon-Kim
method in the framework of the temperature-dependent density functional theory
on the basis of the electron structures. Lastly, we perform the MIMD simulation
to calculate ion features of x-ray elastic scattering for Al.
