Hi all,

Is there any software or E+ addin to run in parallel with EnergyPlus in order to have a graphical variation of my outputs during the simulation? For exp like Trnsys simulation!

Thank you

Thank you Aaron for your help. Didn’t help me! Im searching for a software to visualize the hourly variables graph during simulation

Ah, got it. If you're interested in output variables and not summary reports, then you want to create plots by accessing the ESO file and have it update as the simulation progresses. I am not sure if the ESO file is updated each timestep or written only at the end of a simulation, so I'll let EnergyPlus development team members confirm. @MJWitte@JasonGlazer@MarkAdams@Jason DeGraw

Dear Aaron,

Im very thankful for your help! Could you please tell me how to accessing the Eso file! I would like to try it in all cases.

EnergyPlus writes output variables and output meters to the ESO file after each simulation. You can access the ESO file with many tools (xEsoView, Results Viewer, etc.). EnergyPlus also writes this data to an SQL file, which has many tools to read and view as well. I would recommend searching for "eso file viewer" or "energyplus sql file" on Unmet Hours.

I am not aware of any existing software that displays live data during the simulation. Some of the commercial interfaces for EnergyPlus may have this capability. It is possible to do this using one of the co-simulation options to exchange live data between EnergyPlus and an external process that can display the data. The options include External Interface and Python Plugins (new in v9.3.0, but be sure to get the 9.3.0 bugfix release.
