[CP2K-user] LiC6 Geo Opt (Metallic System)

[Travis]

Is that your initial structure or the one you get after optimization? The 
one you've attached is heavily distorted but not in the way you describe 
above. All of the layers have different separations and one layer is highly 
compressed. Your initial structure should look like the one attached (a 
1x1x1 cell denoted '_111' and a 5x5x5 denoted '_555').
