Dear all;
I am optimize the atom position of a slab using mini. However, It seems that the force could not reach the criterial (the default 2mRy/bohr). It have run many steps. The ENE is also oscillation. Below, I paste the atom force of the last several steps, the slab structue which has optimized several steps and slab.inM. I also adjust the DELTA for several values (z=1.2,1, 0.5 etc) but could not success. So can you give me some advice how to do now? (During mini optimization, the structure still keeps the symmetry, I don't know how to break the symmetry and let all of the element optimized as suggest by Dr. L.D. Marks)
Thank you in advance!
