Dear Prof.Blaha,Thanks for your reply.The reason i use Rkmax 9.5 is that i use the method in Density Function Theory and Family of (L)Apw-methods to get a proper parameters.It is only 9.5 that can satisfy with 0.0001Ry accuracy.So you mean i need to have a lower accuracy in minization?In addition,

First of all: I hope you have done KFe2As2 bulk first. Since it contains Fe, it could be that it is magnetic (FM or AFM ? check literature) and one should use runsp Check out if a magnetic moment persists, this answers your question if you should use run or runsp Why do you initialize with
