服务器为Windows系统,配置为80核,890GB运行内存,
配合物结构为
在ORCA找过渡态时,输入文件开头如下
! BLYP D3 def2-SVP def2/J optTS freq tightSCF noautostart miniprint nopop
%maxcore 26000
%pal nprocs 30 end
%geom Calc_Hess true end
......
out文件正常运行一天时,出错如下,查看轨迹文件得是需要的过渡态方向,这是因为内存和核心没设置合理吗?

在用Gaussian 16计算时,
输入文件如下

运行约几个小时出错,out文件如下,卡在这里计算不了,任务被killed,不知是结构问题还是计算方法有问题,望各种大佬指导一下
