[QE-users] Apply constant velocity using cp.x

[Lu Hailin]

Dear all,


I have designed a model with two self-mated Fe(110) surfaces.  During the dynamic  simulations,the bottom layer of the lower slab (the substrate)  was held rigid, while the upper slab (the counter-surface) was moved at  constant velocity.


How can I apply constant velocity such as 200m/s along the y direction on the upper atoms through the whole progress  using cp.x in Quantum Espresso 6.1. version .


Any help would be appreciated.



Thank you!
Best regards,
