What's the meaning of 'timestep" in HB simulation output

Hi, I don’t understand the option of timestep in HB simulation output. If I want to simulate building load every 15 minutes, what should I do?

Hi @ZYH, that setting controls how often results are reported.

The timestep input here for simulation parameter controls the frequency of the timestep of the simulation.

Often people will set a low simulation timestep to get more accurate results, but to keep the results files small they’ll limit the reporting of results to hourly.

Thank you very much for your help, I think I know how to do.
