By the way, do you want to calculate the FCC structure (diamond structure)? If so, your model/structure is definitely wrong~ For FCC, the primitive cell contains two atoms, one at (0,0,0), another at (1/4,1/4,1/4), and the cell vectors should be as you used. -- GAO Zhe CMC Lab, Materials Science & Engineering Department, Seoul National University, South Korea At 2012-07-18 16:41:23,"bamidele ibrahim" wrote: Dear GAO, Thanks for the explanation, i have tried it , it produced the same result.

Dear Haowei Peng, in my experience this error may happen with GGA functionals when you push the scf threshold very low (let's say conv_thr below 10^(-10) ). Since you're hiding some relevant information of your input file (such as PP files, atomic coordinates and k-points) I cannot be sure if this is causing the problem. In your case conv_thr = 1.0d-8, which is not that low, so there may be other problems, such as a wrong set of coordinates on input, a bad pseudopotential, ... Maybe, you can try to increase the cutoffs.

Thanks all.. and sorry for my sending the mail repeatedly (I kept receiving mails which told me that my mail was not delivered successfully...) finally I set the calculation restart mode to "restart"...and it give a result which seems right, at least the total energy but I have to check the other information. -- Haowei Peng Northwestern University Department of Physics & Astronomy 2145 Sheridan Rd.
