RunModel for hot restart after a previous simulation period

This function allows to restart a simulation at the end of a previous simulation period. Parameters Qinf, Qrelease, and Qmin can be redefined for this new simulation period.

Usage

# S3 method for class 'GRiwrmOutputsModel'
RunModel(
  x,
  InputsModel,
  RunOptions,
  IndPeriod_Run = which(InputsModel[[1]]$DatesR %in% DatesR),
  DatesR = getNextTimeSteps(x),
  Qinf = NULL,
  Qrelease = NULL,
  Qmin = NULL,
  merge_outputs = TRUE,
  ...
)

Arguments

x

Object returned by RunModel.GRiwrmInputsModel, RunModel.Supervisor, or RunModel.GRiwrmOutputsModel

InputsModel

GRiwrmInputsModel (see CreateInputsModel.GRiwrm) or Supervisor (See CreateSupervisor)

RunOptions

[object of class GRiwrmRunOptions] see CreateRunOptions.GRiwrmInputsModel for details

IndPeriod_Run

[numeric] index of period to be used for the model run [-]. See details

DatesR

(optional) POSIXt vector of dates of period to be used for the model run. See details

Qinf

(optional) matrix or data.frame of numeric containing observed flows. It must be provided only for nodes of type "Direct injection" and "Diversion" [m3 per time step]. Column names correspond to node IDs. Negative flows are abstracted from the model and positive flows are injected to the model. See details

Qrelease

(optional) matrix or data.frame of numeric containing release flows by nodes using the model RunModel_Reservoir [m3 per time step]. See details

Qmin

(optional) matrix or data.frame of numeric containing minimum flows to let downstream of a node with a Diversion [m3 per time step]. Default is zero. Column names correspond to node IDs. See details

merge_outputs

logical Merge simulation outputs with the one provided in argument x

...

Further arguments for compatibility with S3 methods

Value

An object of class GRiwrmOutputsModel. This object is a list of OutputsModel objects produced by RunModel.InputsModel for each node of the semi-distributed model.

It also contains the following attributes (see attr):

• "Qm3s": a data.frame containing the dates of simulation and one column by node with the simulated flows in cubic meters per seconds (See plot.Qm3s)

• "GRiwrm": a copy of the GRiwrm object produced by CreateGRiwrm and used for the simulation

• "TimeStep": time step of the simulation in seconds

Details

IndPeriod_Run or DatesR must must be continuous periods starting the time step after the last simulation time step of the GRiwrmOutputsModel object provided through the argument x.

Qinf, Qmin, and Qrelease are used for overwriting the corresponding arguments provided to CreateInputsModel.GRiwrm for the period to be simulated. Therefore, the number of rows of these arguments must correspond to IndPeriod_Run or DatesR lengths.
