Thread-topic: [EnergyPlus_Support] About the output:variable

What I do is to set a condition on the breakpoint like this 

(DataGlobals::WarmupFlag == .FALSE.)

A good place to put a breakpoint to see watch variables right at the end of a timestep is at line 367 in HVACManager.f90, where the call to UpdateDataandReport occurs.

Hello,

Sorry, you are right. I started to compare data after:
Warmuping Up
Warmuping Up
Warmuping Up

So can you tell me how can I do to start to compare data after Warmuping Up {1} Warmuping Up {2} Warmuping Up {3}

Thank you!

Ying Yan

Hello,

True, I started to compare data when the program began to "Starting Simulation...". Thank you.

I can't tell from your screen if the data is for the warmup period or the actual environment.

When you run the simulation you should see:

Many lines of information, then
Warmuping Up {1}
Warmuping Up {2}
Warmuping Up {3}
Starting Simulation...

When the program gets to "Starting Simulaiton..." is when you want to start comparing data.
