【求助】为什么我按照教程操作都会计算失败？
|

刚装了MS4.2, 初学。按照李明宪老师的教程操作计算NaCl的能带，结果如下 难道是license的问题吗？ task : BandStructure continuation : default spin_polarized : false bs_nextra_bands : 12 opt_strategy : Memory page_wvfns : -1 bs_eigenvalue_tol : 1.000000000000000e-005 calculate_stress : false popn_calculate : false calculate_densdiff : false pdos_calculate_weights : true num_dump_cycles : 0 [ Last edited by freshgirl on 2009-6-25 at 17:19 ] |
