ITAP IMDCode for nanowire simulations
Uses: EAM force field
Select “Pipelines” IMDElastic, click on “run“
IMDNanowire
upper
lower z
y x
Crystal dimensions [100][010][001] crystal
Restriction of atomic motion
1=free to move
0=fixed
Displacements in particular direction
Every Nd steps
PBCs in x,y,z direction? 1=yes 0=no
Initial temperature:
Basically ~0 K
.xyz file that makes movie when loaded in VMD
Energy, stress tensor, temperature.. vs. simulation steps – very useful for analysis in Excel or Matlab
First line contains description of content
The following sections contain .png files and .gif animations for views in three different angles
VMD output
VMDMovie.xyz file
In VMD: Click on Graphics Representations
Select “VDW” as “Drawing Method” to plot spheres
This makes it look much nicer
Create snapshot files in File Render: or, alternatively simply take screenshots for your writeup
