Re: Simulate reactangulat monolayer

Have you tried adding unit-cell-category keywords to the .mat file?

Two links with more about the unit-cell-category:

Dear expert, 

I am currently new to using VAMPIRE software. 

I try to simulate a monolayer rectangular lattice with two atoms in a unit cell. However, I found that the VAMPIRE ignored my second atom. 

I got this in the log:

Material 2 makes up 0 % of all atoms ( 0 atoms )

 

I also checked the .xyz file. It did ignore the 0.5 0.5 0 atoms.

I would appreciate it if anyone could tell what I did wrong here.
