Dear all, I would like to perform cell optimization with no temperature using CP2K. I searched for this keyword in mailing list. I didn't find many useful posts in this regard. Since I am new to this type of calculation, can you suggest me few references where this method is used sucessfully ? How should i check the correct value of CUTOFF for my system to carry out this calculation? Any suggestions for carrying out this calculations are greatly appreciated. Thanks & Regards, Sandeep
