  Earlier, normalization conditions for the columns of the PCM (Polarized
Continuum Model) were determined and a method of enlarged surface meshes was
developed. We developed similar methods for the COSMO (COnductor like Screening
MOdel). These methods make it possible to introduce larger surface meshes
without loss of accuracy and perform fast calculations of the solvation energy
and the Born radii in the SGB (Surface Generalized Born) method. In addition,
the corrections proposed in this work provide a significant enhancement in the
accuracy of numerical calculations.
