有没有遇到类似情况的?是ORCA5.0不能用RI加速吗?【至少以下这种方式不行,还是哪里搞错了】
刚安装orca5.0 测试H2分子的优化和频率分析,没有问题。----------------------------------------------------------------
[root@localhost oi]# mpiexec --versionmpiexec (OpenRTE) 4.1.1

[root@localhost oi]# which orca
alias orca='/root/hcp/orca500/orca'

输入文件用multiwfn 转化的inp格式:

但是在用multiwfn中的方法: 5 RI-wB97M-V/def2-TZVP或者
6 RI-PWPB95-D3(BJ)/def2-TZVPP时,计算就会报错,【其他设置都不变】请问这是怎么回事?

本来是打算用RI-wB97M-V/def2-TZVP优化有机镍配合物的结构和频率分析(101个原子,含Ni, N, Si, C, H元素),发现报错,就用该方法尝试了氢气分子的优化和频率分析,发现也报错,但是用B97-3c时就可以正常结束。
