I am using EnergyPlus 9.2 and OpenStudio 2.9 for modeling with an RTU+VAV HVAC system. I initially used the default fan power curve settings and had a successful simulation. However, after modifying the fan power curve to use the ratio of actual airflow to the maximum design airflow, I encountered errors, specifically indicating that surface temperatures are too high. Can someone provide assistance with this issue? Thank you very much."
