I use openstudio 2.1, but i tried also with v1.11. When i start the simulation it gives me this messages: -Initializing workflow. -Processing OpenStudio Measures. -Translating the OpenStudio Model to EnergyPlus.

Then it crashes: with 2.1 stopping at 100% without creating an idf; in 1.11 closing automatically the software. Anyone wo can help me?i already removed every geometry error, verified construction sets. Is it a software, compatatibility error?i use Sketchup2016Pro. OS crashes also if i click on measure tab.

+1 for the avatar. Actually +1000.

I can re-create it crashing when trying to export to an IDF in 2.1, which would also of course cause the simulation to fail. I'll post an answer when I know more.

Update: this is an issue on our end. We narrowed the crash down to the plant loops, but not sure why yet. Once we identify the issue hopefully we can give you a cleaned up model that avoids the issue.

Do you have good news? I really appreciate the hard work you do.

The problem is the missing Loop Temperature Setpoint Node Name field in the Cooling plant. You could delete the cooling plant and re-create, but I can also try to hand fix the file and send it back to you. Might be a few days before I can get the file back to you.

(I'll try to format code block later so readable)

OS:PlantLoop, {83c1f9b2-5811-414c-8788-c6dedaca4112}, !- Handle Cooling, !- Name , !- Fluid Type , !- User Defined Fluid Type , !- Plant Equipment Operation Heating Load , !- Plant Equipment Operation Cooling Load , !- Primary Plant Equipment Operation Scheme , !- Loop Temperature Setpoint Node Name 30, !- Maximum Loop Temperature {C} , !- Minimum Loop Temperature {C} , !- Maximum Loop Flow Rate {m3/s} , !- Minimum Loop Flow Rate {m3/s} Autocalculate, !- Plant Loop Volume {m3} {e1947c24-f48f-4c26-ade2-140a8b9a47b6}, !- Plant Side Inlet Node Name {d1c765e5-2ebf-4d3b-a71e-fa4252cfa43f}, !- Plant Side Outlet Node Name , !- Plant Side Branch List Name {0666917d-ac2b-434b-b6ae-f6a011ef49e0}, !- Demand Side Inlet Node Name {5d2e1a2d-b8d1-45d1-af94-553c74f632bd}, !- Demand Side Outlet Node Name , !- Demand Side Branch List Name , !- Demand Side Connector List Name Optimal, !- Load Distribution Scheme , !- Availability Manager List Name , !- Plant Loop Demand Calculation Scheme , !- Common Pipe Simulation ; !- Pressure Simulation Type

Thank you, now the simulation finally started. How does it happen these kind of problems?There is a way to avoid them?

Not sure, we are at a loss, my guess is that it happened in one of the version translations from 1.11 to 2.1. Best way to avoid it, is to check out run of files after upgrading and save as a new name so you can go back to old version to get any data that was corrupted, this isn't a common occurrence.

Hey, @David I have the same probblem in OpenStudio 2.5, when I try to run a simulation I got this message, when it is 100%: " Initializing workflow. Processing OpenStudio Measures. Translating the OpenStudio Model to EnergyPlus. Processing EnergyPlus Measures. Starting Simulation. EnergyPlus Starting EnergyPlus, Version 8.9.0-eba93e8e1b, YMD=2018.07.20 12:31 **FATAL:Errors occurred on processing input file. Preceding condition(s) cause termination. EnergyPlus Run Time=00hr 00min 0.63sec Program terminated: EnergyPlus Terminated--Error(s) Detected. Failed. " Anyone wo can help me, please?

@Raghda, it doesn't sound like you are seeing the application crash, rather your EnergyPlus simulation is failing. Please open the "eplusout.err" file with a text editor and review severe and fatal errors. Post to a new (or related) topic if you cant identify and fix the cause of the failed simulation.
