We start by creating a list of coordinates using reading the waterlevels at the cell centers (the initial waterlevel values are defined per cell)from a CSV (Comma separated values) file.
Code Block | ||||||
---|---|---|---|---|---|---|
| coordinates = [[cell.Center.X, cell.Center.Y] for cell in fmModel.Grid.Cells]
Then we get the waterlevel for these coordinates at the start time and set them as the initial waterlevel of our model.
Code Block | ||||
---|---|---|---|---|
| ||||
# add initial conditions import csv initialWaterLevels = [] initialCsvFilePathwith = open("D:\\Workshop\\initial.csv" with open(initialCsvFilePath) as csvfile: lines = csv.reader(csvfile, delimiter=',') for line in lines: initialWaterLevels.append(float(line[0])) fmModel.InitialWaterLevels.SetValues(initialWaterLevels) |
To limit the calculation time we change the maximum and initial delta t (time) to 1 hour using the SetModelProperty" function.
Code Block | ||||
---|---|---|---|---|
| ||||
# set model max and initial timestep size timeStep = timedelta(hours=1) SetModelProperty(fmModel, KnownProperties.DtMax, str(timeStep.total_seconds())) SetModelProperty(fmModel, KnownProperties.DtInit, str(timeStep.total_seconds())) |
