About the solvent effect calculation.



Dear ccler
 
I am confused with the PCM calculations.  The system is a bit  too large, about 60 heavy atoms, and the basis number is about 1000.
 
The keyword looks like:
 
 
#P HF/3-21G scrf=(pcm,solvent=2) scf=direct
 
 
Error message looks like:
 

 Too many tesserae.  Increase the MxTs.
 Error termination via Lnk1e in /usr/local/g98/l502.exe.
 
Anyone can give me advices on solving this problem?
 
Best regards
