When the system has ion to perform as drift-diffusion equations, we solve the time dependent drift-diffusion for slow ion move simulation. Since the ion moves may not be governed fermi-level concept. We simply treat is a tradiational drift-diffusion equations.

Ideally, the ion density is given by initial setting. The total ion number should be fixed. The program is aim to model multi-ions drift-diffusion. The command is as following.

$Withionmove

Parametertype,3Mions,3μ p3 p4 Parameters of the 3 layer
 ....

For example: Consider 2 ions, 1st is negative charges, 2nd is positive charges, total 5 Regions we can
