Subject: GAMESS Solvation Problems
Content-Type: text/plain; charset=us-ascii

Dear all,

I am trying to use PCM to do a geometry optimization of
a large molecule (65 atoms, using 6-31G basis set, totally
277 basis functions) in water. The input file is attached
in the following (except the coordinates of the solute because
it is quite lenthy). The check run told me that everything
should be OK. But when I ran it, I got this error message:
 
WARNING : MAX NUMBER OF BASIS FUNCTIONS = 199

This error occurred soon after the 2-electrion gradient was
calculated and then GAMESS terminated. The restriction of
basis set size of GAMESS is 361 if dirscf=.false. or 2047 if
dirscf=.true. It was odd that I got the above error message.
Dose any one have the idea what's happening and how can I solve
this problem? Thank you in advance.

Jeff Klauda
