[EnergyPlus_Support] epw File Wind Velocity edit through Element software





Dear All,

I am in a process of doing some validation studies for Natural Ventilation (wind and stack effect). For the same, i am trying to edit .epw file through element software in order to make some changes in the wind velocity column. After making changes when i run simulation, it throw back some Nan errors. I believe this happens when i "save as" epw file opened in element after making the respective changes. so this is happening during the transition. 

Please suggest how to resolve this error.
