#25 Optimisation - Invalid reporting time: 0 (less than or equal to zero)

[Aymen Hafeez]

Hi,

I am trying to run a parameter otimization on a model. I have structured it similar to the chemeng optimization example 1. I am getting an error saying 'Invalid reporting time: 0 (less than or equal to zero). It also points to the 'run' function, which I have defined as the following:

> def run(**kwargs):
    simulation = simModel1_Opt()
    nlpsolver  = pyIPOPT.daeIPOPT()
    lasolver   = pyTrilinos.daeCreateTrilinosSolver("Amesos_Klu", "")
    relativeTolerance = 1e-6
    reportingTimes = times.tolist()
    return daeActivity.optimize(simulation, reportingInterval       = 1, 
                                            timeHorizon             = 14,
                                            reportingTimes          = reportingTimes,
                                            lasolver                = lasolver,
                                            nlpsolver               = nlpsolver,
                                            nlpsolver_setoptions_fn = setOptions,
                                            relativeTolerance       = relativeTolerance,
                                            reportSensitivities     = True,
                                            **kwargs)

I perhaps don't understand fully how the code works, but any help would be greatly appreciated. I have also attatched the full code.

Thank you in advance.

Hi,

Reporting times include points in time where the results should be reported next (after initialisation at t=0). Just don't include 0 and it should be ok.
