question on two-probe model setting up

[freshgirl203]

I followed the VNL version 200810 tutorial, to set up a Li-H2-Li two-probe system. But I found that the position of the right electrode can not be adjusted indivisually. Everytime I tried to move the right electrode closer to H2 molecule in the middle, the whole left electrode and H2 molecule will move, too.

Please see attached figures.
1st step: I adjusted the distance between H2 to the left electrode


2nd step: I want to select the Li atom nearest to H2 in the right electrode, but everytime all the middel region in white was selected


3rd step: I use "translate" commond, the whole unwanted region moved toward right


If this problems happen to every case, how can we set up a two-probe system successfully? Pls help. Thanks in advance.

It seems your pictures did not get attached to the post.

When it comes to selecting the Li atom, you will not see the actual atom get selected, that's true (and a bit confusing). You just need to have the mouse over it when you right-click to choose translate. Hope this helps.

I think  you can adjust the  position of  two H2, it look like translate the Li....
       I hope this will help you!
