[求助] mp2报错

现在正在尝试用在gaussian03上采用mp2 计算一些弱作用力
尝试了一下一些输入方法
%chk= filename.chk
%rwf=a, 245MW,b,245MW,c,245MW,d,245MW,e,245MW,f,245MW,g,245MW,h,245MW
%mem=4G
# opt freq mp2(direct)/genecp

或者
%chk= filename.chk
%mem=10G
# opt freq mp2(direct)/genecp

filename

电荷数 多重态
分子坐标  

Au Ag 0
sddall
****
C H 0
tzvp
****

Au Ag 0
sddall

但每次都有报错信息
第一种是
Not enough disk for semidirect, minimum= 212717110
Not enough memory for fully direct, minimum= 328387200
Not enough  resources for E2 calculation

第二种是
Disk-based method using ON**2 memory for167 occupieds at a time
Estimated scratch disk usage=578373325440 words.
Actual scratch disk usage=578157617792 words.
Erroneous write. Write -1 instead of 4096
fd = 4
orig len= 4096 left=4096
g_write

有哪位高人能够帮我解决这个问题吗 谢谢了

如果mp2把你折磨的欲仙欲死,不妨看看这个帖子

nothing help. DFT can do little thing to find out the weak interaction. Thanks though.

can you tell more specifically?
Does that mean I need modify this line: %rwf=a, 245MW,b,245MW,c,245MW,d,245MW,e,245MW,f,245MW,g,245MW,h,245MW  ?

Sorry I can't input Chinese on my Linux system. Thank you.

As far as the weak interaction is concerned, DFT is much more accurate than MP2. Your knowledge is too old.

对的,就是改动%rwf这一行,加大硬盘。如果你把硬盘都用了还是不行的话,只能换方法了。其实“鱼妃”说的对,弱相互作用,DFT方法在基组合适的情况下是能描述的很好的。只是MP2一直被公认为很精确的方法,甚至某些审稿人也一样认为。

sorry I just read your link throughout. the information at the very end is really helpful. but I'm still trying to compiling the Gaussian09 version on our system. Hopefully, we can figure it out quickly then I can use the long-range corrected functions on my molecular. Thank you again.

Sorry for the first reply. I'll give you the credit.

I'm not the guy who is on computational chemistry major. So what I learned about DFT are all from xiaomuchong. Meanwhile, there is no professor who can teach this specific area, although someone is so theoretical and does excellent job in his area. ) The concept that DFT can do very little thing in long range interaction is from what I read in recent Angewant and Chem. Soc. Rev. (both are from this year.) Sorry again about my reckless reply at first time. I'll share some my experience after I can run job in Gaussian09 about this long range interaction. Thank you again.
