VASP 运行中的错误

VASP 运行中的错误

Error EDDDAV: Call to ZHEGV failed. Returncode = xx

这是对角化例程的错误。您可以尝试切换到不同的方法(即 ALGO)或使用倒数第二步的位置而不是最后一步。查看结构(例如在 VESTA 中)以确保它仍然看起来像您期望的那样也很有帮助。偶尔会发生两个原子在弛豫过程中彼此靠近的情况。特别要检查离子循环内的所有电子迭代是否收敛。

Office 安装

Office 安装

使用 Office Tool Plus 下载、部署 Office,使用 KMS 激活。

下载安装 Office 有多种途径,可以从 office 官网下载安装,也可以从 Windiws 应用商店下载安装,但这些方法无法自定义安装组件,所以更推荐使用 Office Tool Plus(下简称为 OTP)进行部署。

OTP 下载

下载 | Office Tool Plus 官方网站 (landian.vip)

前言:

随着同步辐射光源的建造,X 射线吸收谱学方法(XAS)得到了前所未有的发展,在物质结构表征(包括原子结构及电子结构等)、理化性能解释(比如单原子催化剂位点研究、In-situ/operando 测试等)都发挥着越来越重要的作用,前沿研究中都经常看见其身影。一直以来,可以说 XAFS 都是基于同步辐射的各种表征手段中同步辐射技术中应用范围最广泛广的技术之一。

找不到指定文件

安装软件时的“找不到指定文件”,由 python 版本、pip 获得的包版本与当前 python 版本、系统不一致导致的。
