Changing an FCV initial_setting during simulation

[astuhlmacher]

Is it possible to adjust the maximum flow rate setting of an FCV during a simulation? For example, I am interested in controlling a FCV to change the initial_setting of an FCV from 0.5 to 0.4 CMS five hours into a 24 hour simulation.

I thought I may be able to do this through a rule using SimTimeCondition but the flow rate in the simulation is remaining constrained by the original setting of 0.5 CMS and it is above the new limit of 0.4 for t=5-24 hours.

Below I have included the code for the rule I tried to add:

import wntr
import wntr.network.controls as controls

# Create a water network model
inp_file = 'networks/Net3_withFCV.inp' 
wn = wntr.network.WaterNetworkModel(inp_file)
wn.convert_controls_to_rules(priority=3) #convert controls to rules

# Modify the water network model
Nt=24
wn.options.time.duration = Nt*3600 # 24 hour scheduling horizon
wn.options.time.hydraulic_timestep = 2 #every 2 seconds
wn.options.time.report_timestep = 2 #every 2 seconds
wn.options.time.rule_timestep = 3600
wn.options.time.pattern_timestep = 3600 # every 1 hour (demand constant over hour)
wn.options.hydraulic.required_pressure = 14.065 #[m]
wn.options.hydraulic.minimum_pressure = 0 # [m]
wn.options.hydraulic.demand_model = 'PDD' # pressure-driven demand
wn.options.energy.global_efficiency = 75

t=5 # Time period where FCV initial_setting is changed
valve1 = wn.get_link('FCV1')
valve1.initial_status = "ACTIVE"

# Adjust the max flow rate through valve
cond1 = controls.SimTimeCondition(wn, '=', t*3600)
act1v = controls.ControlAction(valve1, 'initial_setting', 0.4)
rule_temp = controls.Rule(cond1, [act1v], name='rule_valve1_t{}'.format(t), priority=6)
wn.add_control('rule_valve1_t{}'.format(t), rule_temp) #add rule

sim = wntr.sim.EpanetSimulator(wn)
results = sim.run_sim()

Can you share the modified Net3 model you used to run this example?
