Dear Abdullah Bin Faheem
yes, the SCCS implementation in CP2K requires periodic boundary conditions in agreement to your observation.
Best regards

Subject: [CP2K:13260] Problems with SCCS and non-periodic boundary conditions
Greetings everyone,
I intend to run AIMD of two molecules (polymer with another molecule) with the SCCS implicit model and non-periodic boundary conditions. I used the implicit solvent model as studying solute-solvent interactions are not important for my study.
However, when I do I've noticed that around 50 fs, the ends of a polymer molecule begin to distort unnaturally. When trying the same system with periodic boundary conditions, no such distorting was observed. Does that mean that the non-periodic boundary condition does not work well with the SCCS model?
I have attached the input and output files for all cases. Any help would be greatly appreciated.
Thank you
Best Regards
Abdullah Bin Faheem
