space group change
Posted: Thu Dec 19, 2013 2:22 pm
I have crystal structure of organic compound with space group P21/n with 2 molecules in asymmetric unit and I have tried to do energy minimization by putting ISIF=3, ISYM=1 in INCAR file but output structure is coming with space group P1 and 8 molecules in asymmetric unit. What I should do to get new one in monoclinic system.
