[Wien] The parameters to obtain an accurate small gap

[=?GBK?B?saHP6f6f?=]

Dear Dr. P. Blaha and Wien2k users，


I am trying to calculate a material with a very small gap about 10 meV, and I want to get the value of the gap to be as accurate as possible.
How should I do it? For example, what setting parameters should be set? I know I should use a large K-mesh and set the convergence LIMIT to be small. What else can I do?


Thank you,
Xiangyan Bo
