Multi-run scripts

Auto-generate multiple sequential Delft3D-FLOW models for multiple subsequent (restarting) simulations from a template model

multipleruns.py adjusts the following things in the input files

  • Master Defenition File (.mdf)

    • Adds Restid='identifier'+ run_nr, get's the identifier from the .mdf filename
    • Change smoothing time to zero Tlfsmo = 0.0000000e+000
    • Change times of restart and history files:

    Flmap = T_start output_time_step(remains the same) T_end

    Flhis = T_start output_time_step(remains the same) T_end

    • Due to a bug in Delft3D-FLOW, NetCDF cannot restart a map file from a specific time. Therefore, the index of the output step must be used. This is restart time step is calculated automatically and added with Restid_timeindex keyword and value. This is the only way to restart from a netCDF map file!

  • Morphology .mor file

    • Resets morphological smoothing time MorStt = 0

  • .bcc, .bct, .sed files

    • Adds duration of one simulation to all time steps
