Geometry not updated
Hi I'm having a similar problem to the one outlined by Niel here. When I run Cosmo geometry
optimization jobs my geometry is not updated and my output also lacks the "@ lines" Niel mentions.
My input is as follows:

In this particular input I use the default values for the solute atom radius parameter, but I have
experimented with "set cosmo:map cosmo.par" as described in the documentation. Is there a highly
recommended fix for this problem?
