Witryna大家好，我计算一个体系能量时，静态自洽计算的设置是 encut=400 istart=0 icharg=2 ismear=0 sigma=0.08 nsw=0 ediff=1e-5 ediffg=-0.05请问有什么问题吗？我的ediffg是负数，力的收敛标准，我原以为力的收敛标准只在优化结构的时候用，按理说静态自洽计算时不用设置这一项吧，那这里会对我的结果有什么影响吗？ Witrynaismear – The smearing parameter used by the step_func. Returns: Array of size nx with delta function on the desired outputgrid. Return type: np.array get_step(x0, sigma, nx, dx, ismear) [source] Get the smeared step function to be added to form the spectrum. This replaces the SLOT function from VASP. Parameters:

GW calculation Files for this section can be found here GW calculations can run in parallel, but only across k-points using KPAR. Therefore NCORE or NPAR > 1 will not work for GW. WitrynaFor relaxations in metals always use ISMEAR=1 and an appropriated SIGMA value (the entropy term should less than 1 meV per atom). Mind: Avoid to use ISMEAR>0 for semiconductors and insulators, it might result in problems. For metals a sensible value is usually SIGMA= 0.2 (that’s the value we use for most transition metal surfaces).
