[Pw_forum] CuO bulk Error during compilation

[GAO Zhe]

Since you defined there are 2 types of elements, but in ATOMIC_POSITIONS, you defined 3 kinds, i.e., Cu1, Cu2 and O1.
You have at least 2 choices. 1, remove the number behind elements' symble and combined Cu1 and Cu2 as one element, Cu; 2, change the parameter ntyp from 2 to 3.

Dear all,

  I tried to compile bulk CuO SCF calculation using following input file, which i built.........

     from read_cards : error #         5
     species O1 in ATOMIC_POSITIONS is nonexistent

     stopping ...


I dont understand why, evenwhen i visualize using VESTA or xcrysden, there is no problem in getting right monoclinic structure. Kindly suggest where is problem.



Thanks
