[CP2K-user] [CP2K:13280] SCCS Solvation Model Implementation - Molecule Radii Explodes

[Dev Rana]

I take back what I previously said. The 0th geo opt step finishes quickly 
with SCF steps taking 20-25s each. The 2st geo opt step does not finish and 
each SCF step takes 5+ minutes. Here's my input file and output for that.  
I'm also running this on GPU. 

What do you advise? I've attached the input output files and paste input 
below. The convergence values keep increases, rather than decreases. And 
Total Energy keep lowering.
