The teacher asked me to add vibrations to the original in file and let the upper atomic group vibrate. I’ve added the code from the manual to the original in file, and variable A is equal to 10.0
Variable T is equal to 5.0
The variable omega is equal to 2.0PI/$T
Variable x equals swiggle(0.0,$A,$T)
Variable v equals v_omega($A-cwiggle(0.0,$A,$T))
Fix 1 Boundary Shift Variable v_x NULL NULL v_v NULL, but the final result does not cause the upper atomic group to vibrate. I would like to ask where the problem could be, and I would appreciate it if there was an in document on vibration that I could learn from.
Then you should first and foremost discuss this with your adviser, who knows you and your research much better than some random person on the internet.
How can you tell?
Are you sure you are not looking at the system on timesteps that are a multiple of the vibration period?
Okay, I’ll discuss it with the teacher again, because the previous discussion didn’t come to fruition.
