Re: Problem in CPCM geometry optimization

Alex Granovsky

Hello,

Analytic CPCM gradient are not currently programmed while gradients
are required for geometry optimization. You either need to optimize
a geometry using DPCM (for which analytic gradients are available)
or using numerical gradients.

Kind regards,
