how to run EnergyPlus FMU through PyFMI
I wrapped one energyplus reference building into FMU and try to simulate the Energyplus-fmu using Pyfmi. My EnergyPlus has 60 seconds as the timestep size.
It looks like it can not go through. Any insightful comments are thankful.
The error i got: File "test_fmi2.py", line 15, in <module> status = model.do_step(current_t = t, step_size= step_size, new_step=True) AttributeError: 'pyfmi.fmi.FMUModelME2' object has no attribute 'do_step
The code snippet i am using is as below:
from pyfmi import load_fmu
model = load_fmu("MyEnergyplus.fmu")
start_time = 0
final_time = 60.0 * 60 * 24 * 3 #seconds
step_size = 60 # seconds
opts = model.simulate_options()
idf_steps_per_hour = 60
ncp = (final_time - start_time)/(3600./idf_steps_per_hour)
opts['ncp'] = ncp
model.initialize( )
t = 0
status = model.do_step(current_t = t, step_size= step_size, new_step=True)
How did you wrap the EnergyPlus reference building as an FMU? Which version of PyFMI are you using?
Thanks. I didn't use EnergyPlusToFMU to create those FMU, instead i created FMU from FMI. I am using PyFMI version 2.5.3.
