Re: [EnergyPlus_Support] Weather file in College Park
Based on the last data in the csv output file, the run is terminating on 04/19
sometime between 16:00 and 17:00. The weather data for these hours is very hot
and dry 31-32C (88-90F) and RH 14%. The Dulles weather file RH never drops
below 20% RH during warm weather. I suspect that the hot dry weather may be
triggering the iteration problem. I will forward this to another team member
to determine why the DX coil model is struggling with this simulation.
