3.9.21D Domains or ESTRY.exe Control File (.ecf File)

The 1D domains or ESTRY.exe Control File (.ecf file) sets simulation parameters and directs input from other data sources for all 1D domains. An example of a simple .ecf file for a 1D only model (ie. no 2D linkage and simulated using ESTRY.exe) is shown below. The example as is used if there are 1D domains in a 2D/1D model is shown further down.

! Set the geographic projection

MI Projection == CoordSys NonEarth Units "m" Bounds (-10000.000,-10000.000) (10000.000,10000.000)

! Set simulation time parameters

Start Time (h) == 0.0

End Time (h) == 10.0

TimeStep (s) == 30

Start Output (h) == 0.0

Output Interval (h) == 0.5

! Read in the 1D network

XS Database == m11.txt ! using a MIKE 11 processed data file for X-sects

Read MI Network == ..\model\mi\1d_nwk_example.mif
! Set the initial water level

Set IWL == 1.

! Read in the boundary condition locations and values

BC Database == ..\bc dbase\bc_dbase.csv

BC Event Text == __event__

BC Event Name == Q100

Read MI BC == ..\model\mi\1d_bc_example.mif

For a 2D/1D model, the control file for the 1D domains for the same .ecf file above would look something like the below. Note that a number of the commands are not needed as they would have been specified in the .tcf file. Commands that are only relevant for 1D only models are indicated with a “1D Only” underneath the command in Appendix B.

# This is an example of a simple .ecf file used for a 2D/1D model run
! Set simulation time parameters

Start Output (h) == 0.0

Output Interval (h) == 0.5

! Read in the 1D network

! Set the initial water level

Set IWL == 1.

! Read in the boundary condition locations and values

Read MI BC == ..\model\mi\1d_bc_example.mif

Appendix B lists and describes .ecf commands and their parameters.
