Gamess能量分解的不收敛问题

molx79

Gamess初学，感觉好难呀。我的输入文件如下： $CONTRL SCFTYP=RHF RUNTYP=eda ICHARG=0 ispher=1 mplevl=2
  pp=read MULT=1 $end
!$guess guess=hcore $end
$BASIS basnam(1)=metal,metal,ligS,ligC,ligS,ligH,ligH $END
$LMOEDA MATOM(1)=3 4 MCHARG(1)=0 0 MMULT(1)=1 1 $END
!$SCF DIIS=.t. SOSCF=.f. DIRSCF=.T. FDIFF=.F. NPUNCH=1 $END
$scf maxdii=100 $end
$SYSTEM TIMLIM=99999999 MWORDS=2000 memddi=2000 $END

以下是基组信息,不一一列出。
备注：其分子构型是高斯计算的结果，方法基组一样。
一直出现：

The error is most likely to be in the application, so check for
input errors, disk space, memory needs, application bugs, etc.
ddikick.x will now clean up all processes, and exit...

ddikick.x: Sending kill signal to DDI processes.

unset echo。



但是有点体系例如SCl2和HCHS能算成功。
拜托各位老师指点迷津。不胜感激。
