Hi,
I am very new to material studio. I have to perform lattice dynamics study of amorphous aluminum via GULP module of Material studio.
I have been trying to create an amorphous structure. I have generated a nanostructure, altered lattice dimensions, deleted the carbon atoms then packed by aluminum atoms (using packing of amorphous module).
It looks like amorphous aluminium, however, it yields negative elastic constants.
Any idea how to create an amorphous metallic structure and then run GULP ?
Thanks.
