RE: [gmx-users] Viscosity calculation using cos_acceleration

Hi, I fixed an issue with the 1/visc output in 4.5.4, but incorretly. I filed a bug report and a fix, you can easily correct your numbers: http://redmine.gromacs.org/issues/1244 https://gerrit.gromacs.org/#/c/2370/ Thanks for reporting this. Cheers, Berk Date: Thu, 11 Apr 2013 16:55:37

There have been several bug fixes related to viscosity calculations since the release of version 4.5.3, of which at least one (on 1/10/2011) specifically mentions zero viscosity in the .edr and .log files. I would suggest pulling the latest release-4-5-patches from the git repository and
