ensemble (mirror)

This keyword is employed to configure a momentum mirror shock wave simulation, where atoms are deflected by a moving momentum mirror to generate a shock wave.

The direction of the shock wave is along the x axis.

We recommand to use it with the dump_piston keyword.

Syntax

The parameters are specified as follows:

ensemble mirror vp <vp> thickness <thickness>

• <vp>: Indicates the velocity of the moving mirror in km/s.

• <thickness>: Defines the thickness of the fixed region in the other side of the cell. Its unit is Ang. This keyword is optional with the default value 20.

Example

ensemble mirror vp 5 thickness 30

This command makes the mirror moving at 5 km/s in x direction. The thickness of the fixed region is 30.
