[CP2K-user] My CP2K problem didn't converge with vibration

Try lowering the energy gap to 0.001 au. The FULL_ALL preconditioner 
requires an energy gap much lower than the material's band gap. 0.1 au is 
greater than the band gap of MoS2 from Materials Project, which may be 
leading to your observed instability.
