I am running a simulation on Windows using EnergyPlus 9.4.0. At the end of simulation, i got some weird message:

ReadVarsESO program starting. At line 988 of file D:\a\EnergyPlus\EnergyPlus\src\ReadVars\ReadVarsESO.f90 (unit = 22, file = 'C:\Users\projects\xprojects\code_simu\code..\simulation\output\EPout.csv') Fortran runtime error: Cannot write to file opened for READ

Error termination. Backtrace:

No idea if it's the cause, but I noticed the path C:\Users\projects\xprojects\code_simu\code..\simulation\output\EPout.csv. Sometimes when the file path is really long on Windows, it can cause weird behavior. Maybe you can try moving your simulation files so they aren't buried within so many subdirectories?

EDIT:

I actually just hit this error myself. Another possibility is that the EPout.csv file from a previous run is open in an application (like Excel) and therefore EnergyPlus can't write the new file. That would explain why the error says "Cannot write to file opened for READ".

I'll take a guess at the "code.." folder name. @ep_user, try a clean path with no special characters.

Ah, an open excel file, that makes more sense.

thanks. You are right. I opened an EPout.csv while my model is running. @shorowit
