Afraid this may come off as a silly question, but how can we tell if the version of Star-CCM+ that we are using is mixed or double precision? I've encountered the divergent AMG solver, which gives the suggestion that "this may indicate double precision version is needed." Making a finer mesh has usually resolved this issue, but I am wondering if my version is indeed mixed precision or if that warning just comes up regardless. I am using Star-CCM+ 13.04.011 win64, if that helps.

The double precision version would have a "-R8" after the version number

Thank you, this is exactly the answer I've been looking for. Turns out I have been using the mixed precision version.
