[EnergyPlus_Support] Slab auxiliary program calculation

["philcook76" <philcook76@xxxxxxxxxxx>]

I am trying to use the Slab auxiliary program to generate the ground temps beneath the slab in my building. I am using the weather file AUS_NSW.Sydney_RMY.epw and my idf fiile is copied below (modified from the example). The program starts and gets up to Autosize Grid then something about files and just closes. There is no GER file generated and the OUT file looks fine to me but the GPT file is blank. Any ideas what is going on?

Thanks a lot for your help,
Phil.
